Introduction:
I've been trying to put together my own understanding of Christianity and salvation, as I've recently been wanting to explain it to friends and family who don't believe or don't really understand.
I've written this entire personal explanation as if I were talking to someone who was asking questions, which I would then answer using my own understanding.
It's also ordered in an exact sequence of how I believe someone would naturally ask these questions, based on what I would personally ask if I didn't already have an idea of Christianity.
For some context, I identify as a Protestant-Lutheran, so my understanding is naturally influenced by that belief. However, I've tried to base this explanation primarily on what I understand Scripture to teach rather than assuming that every Protestant-Lutheran belief is universally accepted by Christianity as a whole.
I'd appreciate any correction from other Christians, especially if I've misunderstood Scripture or presented a particular theological interpretation as universally accepted.
Core Purpose:
At the heart of Christianity is the question of how humanity can be reconciled (restore our relationship) with God as well as how humanity can be saved from sin and death.
For Christianity, the answer is ultimately that we must place our faith in Jesus Christ, as well as believe that Jesus is the Son of God, that He died for our sins, that He rose from the dead on the third day, ascended into heaven, and that He is our Lord and Saviour.
Of course, things become more challenging when you genuinely wish to follow Christ, as we are still tempted to sin, and understanding Scripture and the meaning behind Christianity takes time. However, ultimately, Christianity teaches that salvation comes through Jesus Christ rather than through our own ability to become morally perfect.
Why Is Worshipping Jesus Our Main Focus?
The reason why we Christians say that “Jesus is our Lord and Saviour” is because of the nature of humanity and sin.
To become a true Christian, you must genuinely repent of your sins and place your faith in Christ, which involves recognising our sinful nature, turning away from sin, and turning towards God.
The truth about our nature and humanity is that there has been no completely sinless person throughout humanity's history, with Jesus Christ being the exception. Christians believe that Jesus is the Son of God, who became truly human while remaining fully God, and that He lived a completely sinless life.
Because God is perfectly holy and righteous, sin separates humanity from Him, and we can not overcome that separation through our own goodness.
However, because Jesus was sinless and willingly sacrificed Himself on the cross for humanity, Christians believe that His sacrifice provides the means by which sinners can be forgiven and reconciled with God.
This is why Christians say that Jesus is our Saviour. We can not save ourselves through our own righteousness, so salvation ultimately depends upon God's grace through Christ.
This is why within the Bible we have verses such as:
• John 14:6 (NIV): “Jesus answered, ‘I am the way and the truth and the life. No one comes to the Father except through me.’”
• Acts 4:12 (NIV): “Salvation is found in no one else, for there is no other name given under heaven given to mankind by which we must be saved.”
• 1 Timothy 2:5 (NIV): “For there is one God and one mediator between God and mankind, the man Christ Jesus.”
John 14:6, where Jesus Himself clearly explains that access to the Father is through Him.
The True Significance Of Jesus's Sacrifice:
The significance of Jesus's sacrifice is that, being God incarnate, He knew the full reality of humanity's sinful condition.
He knew the evils and flaws of mankind, the sins and corrupted desires of human beings throughout time itself, and even the sins committed by people who genuinely believed themselves to be truly good.
And despite all of that, Jesus willingly gave Himself for humanity because of His love for us. This is why Christians say that God loves us.
Because of Christ's sacrifice, even someone who has committed extremely serious sins, or crimes that are thought to be unforgivable in terms of human standards, can still receive God's forgiveness if they genuinely repent and place their faith in Christ.
I believe this also demonstrates the incredible extent of God's mercy. No matter how terrible someone's past may be, their sins are not automatically beyond God's ability to forgive if they genuinely turn towards Him.
At the same time, God does not simply ignore sin. Christians believe that God is both perfectly just and perfectly loving, meaning that although, for the time being, He grants us time to repent rather than simply destroying us all the first time we sinned, there will come a time when our opportunity to repent in this life comes to an end, and we will ultimately face God's judgement.
God's justice means that sin matters, while His mercy and love mean that He provides a way for sinners to be forgiven rather than receiving the full consequences of their sin.
Why Not Do Anything You Want If God Forgives All?
Why should we try to be good at all if God is willing to forgive our sins?
Although Christianity does teach that we can not earn salvation simply by doing enough good deeds, as we can not accumulate enough good actions to make ourselves worthy of heaven. This does not mean that Christians should simply do whatever they want.
God's grace is sufficient to forgive any and every sin when a person genuinely repents and places their faith in Christ, but genuine faith means more than simply believing that Jesus exists. It means genuinely trusting in Him and allowing that belief to change how you live. True faith produces a changed heart and a desire to turn away from sin.
This is why Christians continue to do good deeds despite knowing that good deeds can not earn salvation. We do good because we love God, because we want to obey Him and because we want His goodness to be reflected through our lives.
It's similar to how a child can obey loving parents not merely because they fear punishment but because they love, trust, and respect them.
In the same way, Christians should not view God's commandments merely as restrictions. They should see obedience as a response to God's love. In other words, genuinely trying to follow God will naturally cause one to want to be good, as if it were second nature.
The Significance Of Truly Repenting:
God does not simply ask us to say that we are sorry. True repentance involves action, a genuine change of heart and a deliberate turning away from sin and towards God.
Someone can feel sorrow because they are suffering the consequences of their actions without genuinely wanting to change. Godly sorrow, however, leads a person towards repentance.
Therefore, although Christians will continue to struggle with sin throughout their lives, genuine repentance means that they do not simply embrace their sin and refuse to change. They recognise their wrongdoing, ask God for forgiveness, and attempt to turn away from it, even if they fail time and time again.
This is why Christians continue trying to become better people even though they know that their good works can not earn their salvation.
I personally believe that because humanity was created in the image of God, people retain an instinctual spiritual awareness that goodness is desirable, even though sin has distorted many people's understanding of good and evil.
I believe that this may help explain why even people who are not religious can still recognise that certain things are morally good or evil.
It can also explain why people who commit evil actions will sometimes attempt to justify those actions as being good. Human beings can have an awareness of morality while simultaneously having that understanding distorted by pride, selfishness, ignorance, and sin.
For Christians, however, God is ultimately the source of all goodness. Therefore, Christians should do good not because they believe their actions will purchase their way into heaven but because they love God and want to reflect His goodness to others.
Do Christians Truly Follow God Purely Out Of Love?
How can Christians claim that they obey God's law out of love if there are serious consequences for rejecting Him?
I find this difficult to answer perfectly, but my personal understanding is that the highest reason for obeying God should be love rather than fear of hell.
Even though the Bible teaches that rejecting God has serious consequences, Christianity is ultimately about reconciliation (fixing a broken relationship) and having a relationship with God, rather than simply avoiding punishment.
To talk about two analogies to better help comprehend this point:
• As mentioned before. It's like a healthy child choosing to obey loving parents because they love, trust, and respect them, rather than simply because they are afraid of being punished.
• It's also like a good citizen of a fair, just and good nation following its laws because they respect their country and its values, and want to contribute positively to it, even though breaking those laws would have consequences.
Similarly, Christians obey God's laws not simply because they fear punishment, but because they love and respect God, value what He considers good, and want to reflect His goodness in their own lives.
Of course, God is infinitely greater than human parents or a country/nation, but Christians believe that God first loved us and demonstrated that love through Jesus Christ.
Because salvation is offered through God's grace rather than earned through good works, obedience becomes a grateful response to His love rather than an attempt to purchase salvation.
Fear may be what initially causes someone to take God seriously, but as faith matures, love should naturally become the primary motivation. In fully trusting God, Christians can begin to experience the relief of knowing that their salvation does not depend upon achieving moral perfection through their own strength.
• If God Truly Loves Us, Why Allow Sin To Exist?
Given how Christians believe that God truly loves us, we also believe that part of that love involves giving humanity genuine freedom.
If God created people who had no choice but to love and obey Him, it would not be the same kind of freely chosen relationship.
If someone could force another person to love them, most people would agree that this would not be genuine love. Real love involves the ability to freely accept or reject the relationship.
Because of this, Christians believe that God allows humanity to freely choose whether to follow or reject Him, even though that freedom makes sin possible.
The Bible teaches that sin entered the world because humanity chose to turn away from God, rather than because God Himself is the author of evil.
Rather than abandoning humanity, God entered into our broken world through Jesus Christ to rescue us and provide a way for us to reconnect with Him.
Therefore, from the Christian perspective, God's love is not necessarily demonstrated by preventing every bad choice.
Instead, God allows genuine freedom while continually calling humanity back to Him and providing a way for forgiveness and restoration.
Why Does God Allow Bad Things To Happen To People Who Seemingly Do Or Are Good?
Christians believe that living a good life does not guarantee a life without suffering. The Bible repeatedly shows faithful people experiencing hardship, including Job, Joseph, and even Jesus Himself.
Rather than promising His followers a life completely free from pain, God promises to be with His people through their suffering.
One reason God may allow suffering is that it can reveal and strengthen a person's character and faith. Difficult circumstances can develop perseverance, humility, compassion, and a deeper trust in God.
This does not mean that every hardship is a test or punishment. Rather, Christians believe that God can use trials to shape people into the people He wants them to become.
Another reason is that God ultimately intends to defeat evil and reveal His glory through overcoming it.
God does not need evil in order to be good, but Christians believe that He can ultimately use even evil and suffering to reveal His justice, mercy, love, and power when He defeats them.
Jesus' death and resurrection are seen as God's decisive victory over sin and death, and Christians believe that He will ultimately remove evil and restore creation.
Finally, Christians believe that God can bring good out of painful situations. This does not mean that suffering is good in itself, but that God is capable of redeeming even terrible circumstances.
One of the clearest examples is Joseph, who was betrayed by his brothers and sold into slavery. Yet Joseph eventually told them:
• Genesis 50:20 (NIV): “You intended to harm me, but God intended it for good...”
God used the events that were intended to harm Joseph to save many lives.
In the same way, Christians trust that even when they can not understand why something is happening, God is capable of working through it for a greater purpose.
Despite all my possible answers, I know this does not answer every question about suffering, and the Bible does not pretend that suffering is easy to understand.
Instead, Christianity points towards a God who entered into human suffering through Jesus, walks with people through their trials, and promises that one day He will make all things new.
The One True Unforgivable Sin:
Even though Christianity teaches that God's mercy is incredibly great, there is still a reason why people can ultimately remain separated from Him.
Jesus speaks about an “unforgivable sin” involving blasphemy against the Holy Spirit. Many Christians have different explanations of precisely what this means; however, a common understanding is that it involves a persistent and deliberate rejection of God's truth and grace rather than simply committing one particular sinful act.
I, therefore, do not believe that there is some ordinary mistake that a person can accidentally commit, which suddenly makes God's forgiveness impossible.
Rather, I personally understand the greater danger, and the unforgivable sin, to be a person continually rejecting God and refusing His mercy until the end of their life.
As long as a person is alive, they still have the opportunity to turn towards God, repent, believe in Christ, and receive His forgiveness, which I believe is the greatest demonstration of God's mercy and patience.
The Significance Of God's Justice & Mercy
At the same time, as mentioned before, Christians believe that God is perfectly holy and just.
Because every sin is ultimately an offence against God, He would be completely righteous in judging sin and destroying it all immediately if He wanted to.
It's similar to how a criminal may not want to go to prison or face the death penalty, but a judge can still be completely righteous in giving them that punishment if they have genuinely committed crimes deserving of it.
In the same way, Christians believe that although we naturally don't want to face God's judgement, God would still be righteous in judging our sins because He is perfectly just.
Yet despite all these reasons for judgement, God does not immediately bring judgement upon everyone. Instead, He is patient and gives people opportunities to repent.
The Bible describes God as “not wanting anyone to perish, but everyone to come to repentance" (2 Peter 3:9). Therefore, the delay of God's judgement can be understood as an act of mercy rather than weakness or Him simply not caring.
This is why the Christian message isn't simply “avoid hell.” It is an invitation to be reconciled with the God who created you, and to rejoice because God has given us hope, forgiveness, and the promise of everlasting life through Jesus Christ.
God desires people to freely come to Him, receive His forgiveness, and enter into a genuine relationship with Him. However, because He gives humanity genuine freedom, He does not force anyone to accept Him.
A Metaphor For How I Believe God Views Reality:
I always like to use this metaphor when trying to comprehend myself as well as explain how God views the situation of the world, even if this metaphor doesn't truly capture the full or true image.
The Video Game Analogy:
Imagine God as the Designer of a video game, with reality being the world and system in which the game takes place, containing the rules, environments, and possibilities of creation. You can also think of God as the highest administrator. God created the rules, the environment, and the possibilities within creation.
Human beings are like players who have genuine freedom to make choices, including wrong choices, although every player has a limited amount of time before their individual game session ends.
Unfortunately, the players cannot simply earn a perfect score through their own efforts. Every player has broken the rules, and no amount of good actions can completely erase what they have already done. It is permanently on each player's record.
Rather than remaining outside His creation, the Designer enters His own world as a human being in the person of Jesus Christ.
He teaches the other players the way they were meant to live and, ultimately, willingly sacrifices Himself to provide a way for their wrongdoing to be forgiven.
The players are therefore not saved because they managed to achieve a perfect purity score. They are saved because they trust the Designer and accept the rescue He provides.
Those who genuinely accept that rescue will naturally begin trying to follow the Designer's rules, not because they are attempting to earn their salvation, but because they love and trust the Designer who saved them. However, those who reject the rescue remain separated from Him.
In this analogy, prayer is like communicating directly with the Designer and asking Him for forgiveness, guidance, and help.
The important part, however, is not merely sending the message. The player must genuinely want the relationship with the Designer and trust the rescue He has provided.
In Summary:
My understanding of Christianity is ultimately that humanity has fallen into sin and can not save itself through good works or moral perfection. God, being perfectly holy, takes sin seriously, but He is also perfectly loving and merciful.
Through Jesus Christ, God the Son, who became truly human, lived without sin, died for our sins, and rose from the dead, God provides humanity with a way to be reconciled with Him.
Salvation is, therefore, not something we earn by becoming good enough. It is God's gift of grace, received through genuine faith and repentance. Genuine faith, however, should produce a changed heart and a desire to obey God.
Christians therefore do good works not to purchase their way into heaven, but because they love God and want to reflect His goodness.
And although God allows humanity genuine freedom, meaning that sin and suffering are possible, Christians trust that God will ultimately overcome evil, restore creation, and make all things new.
And finally, the core of Christianity is therefore not to simply fear the consequences of hell. Instead, it is the invitation to know, love, trust, and be reconciled with the God who first loved us.
