This is an important question for Christians to answer. It can be a stumbling block for many who want to believe in Christianity if they see God as unfair or unjust. Many want to say that there is another way. Some will say that sincerity, even misplaced toward another religion, is enough to get to heaven. How is a Christian to answer this with both truth and grace?
There’s much that could be said here, but here is an introduction to the topic that I believe is both Biblical and rational.
I’ll start by saying that nobody ever goes to hell for not believing in Jesus.
That may shock some people, but hear me out. Nobody goes to hell from a lack of belief in Jesus. Just like nobody ever died of not getting CPR, nobody goes to hell for not believing in Jesus. People die of diseases or injuries. People go to hell because of sin. There will be no one in hell who can honestly say they don't deserve it. We all have sinned and we all deserve hell. So it’s an important distinction to make. Those in hell are there because of the sins they chose to commit. They had a terminal disease called sinfulness, and it caused spiritual death.
Of course, this doesn’t answer the underlying question of whether or not people can be saved apart from Christ. Obviously, the real issue here is whether or not lack of Jesus, the cure for the disease, results in a person going to hell.
The short answer is yes.
The Bible is crystal clear that salvation is through Jesus alone. There is only one mediator between God and man (I Timothy 2:5). There is no other sacrifice for sin (Hebrews 10:26). There is only one Son of God (John 3:16-18, 36). He only came once (I Peter 3:18). The death of a mere man cannot save anyone (Romans 8:3, 13-18, I Corinthians 15:50). Thus, only Jesus could pay the penalty for sin and redeem us.
But what about those who haven’t heard of Jesus? Is God unfair to withhold salvation from them? Did He give them no chance?
The Bible is clear that all mankind has some knowledge of God. Read Romans 1:18-21 and Psalms 19:1-4. These passages, among others, tell us that mankind knows, from the creation, that there is a God. It is obvious to all people that there must be a Creator, even if they reject this knowledge. They can also deduce attributes about the Creator from His creation. For example, because creation is orderly and purposeful, we can see that God is a God of order. He doesn't do things sloppily or without purpose. We can see that He is consistent because nature is steady and predictable. We can see that He values beauty, etc.
In addition, humans have an innate sense of morality (Romans 2:14-15). The Bible refers to this as the law written on the heart. We instinctively know right and wrong, at least in a basic sense. But if there is a moral law, there must be a moral lawgiver. There must be an ultimate moral authority.
These things are evident to all people. The information is out there for people to know there is a God and to seek Him. They have no excuse if they ignore this information and fail to seek God.
Of course, having a general knowledge of God doesn’t mean we have an innate knowledge of salvation. What we know initially from nature will only get us so far. We have to seek God. We have the first piece of the puzzle, but we need the rest of it to know how to be saved. Knowing there is a God out there somewhere is just a beginning. We have to learn more. That's why it's our responsibility to seek God.
Of course, God is also seeking us, which makes the whole thing possible. We could never figure it all out on our own. That's why He revealed Himself in the Bible. And even if we could figure it all out, knowledge alone can't save us. A person can know how to be saved and still not be saved. So we have to rely on God to reveal what we need to know in order to be saved.
We also know that God
wants everyone to come to Him (II Peter 3:18). The very reason that God
created mankind is because He wanted to have a relationship with us. He doesn’t
make people to populate hell with no chance of salvation. He gives everyone a
chance.
Because God wants all to come to Him, God will reveal Himself to those who seek Him. The Bible says that those who seek God will find Him (Jeremiah 29:13, Matthew 7:7-8). God will see to it that those who want to know Him will find the information they need to know to accept Jesus. He can send missionaries or a radio broadcast or a Bible or any number of other messengers to give people the knowledge of how to accept Christ. It is also quite possible for Jesus or an angel to appear (as Jesus did to Paul, for example) to people who don't have another way to hear the gospel and are seeking God.
Of course, God has no responsibility to go to such lengths for those who have failed to seek Him. We all have enough general revelation from nature and our own inbuilt knowledge of God to realize our need to seek him. It is our responsibility to act on what we know.
The principle is that, if we act on the revelation we have, God will give us more. For example, there have been many cases of missionaries being led to go to a remote location and finding there someone who has been seeking God and asking for truth. There have been cases of people hearing a radio broadcast or meeting a stranger who shared the gospel. The Ethiopian eunuch in Acts 8 was seeking God, and God brought Philip to tell him how to be saved. These are just a few examples. God brought these people the knowledge of Christ they needed when they sought Him. He will not turn away any who truly seek Him (John 6:37).
Those who don't act on the knowledge of God they had may never hear of Jesus, but their condemnation will be just because they did not act on the revelation they had. They will go to hell, not because they had never heard of Jesus, but because they rejected what they did know of God.
For those who predated Christ, the way of salvation is faith in God's promise to send a Messiah. So they were saved through faith in Jesus that looks forward to Him. This is the case for Abraham, for example, who "believed God and it was counted unto Him as righteousness." There may also be some who lived after Christ who were also saved in this way, through faith that God would send the promised Messiah (even if they did not know he had already come). But every person who is saved is saved through Jesus Christ. There is no other way.
So, if Jesus is necessary for salvation, then sincerity isn't enough. Belief isn't enough. You have to believe in what is true. You have to follow the one true God and His one way for salvation. If one could be saved simply through sincerity, even if the religion was false, then there would be no need to preach the gospel or teach people about Christ. Just tell them to be sincere. Tell them to be honest. Tell them to follow their own native religion. Blend in, don't rock the boat, be a good person. But not once is this ever used by the followers of God in the Bible. It is always a case of calling people to leave their false religions and follow the true God.
The early Christians were murdered in horrific ways because they refused to follow their native religions and instead were determined to follow Jesus. If salvation were possible by simply following one's native religion, then all these martyrs died in vain. They should have simply gone with whatever would make them happy or not gotten them killed if they could be saved simply by following any old religion. But they knew that salvation only comes through belief in the one true God and in Jesus Christ. They were willing to die in order to have Christ and salvation because they knew there was no other way.
So, we see that the Bible is clear that salvation is only through Jesus, but why is that so important?
The reason we need Jesus is that we can't get to God on our own. We can have all the knowledge in the world, but we can never be worthy of salvation. We're flawed. We have all sinned (Romans 3:23). Sin taints us so that we can't stand in God's presence. God is perfect and holy. Sin cannot abide in His presence. So our sin separates us from God. It's a gulf that can never be crossed because no one can go back in time and un-sin. And good works, no matter how great, can't erase the past.
We all deserve death and separation from God forever because that is the penalty for sin (Romans 6:23). There is only one way for God to be just and judge sin, and yet extend mercy to us who don't deserve it. That one way is Jesus. Jesus lived a perfect life. He was never tainted with sin. So He alone has the right to stand before God and live in His presence. Yet He died, and was separated from God the Father, in our place. When we let Jesus take our place, surrendering our life to Him, He swaps with us - His life for the death we deserve. It's the only way for both justice and mercy to be satisfied. The debt for sin is paid - a debt we could never pay - and we can live with God. Justice and mercy.
Since no mere man could ever live a perfect life, no mere man can save us. It had to be the perfect Son of God. It had to be God in a human body. It had to be Jesus.
Because God wants all to come to Him, God will reveal Himself to those who seek Him. The Bible says that those who seek God will find Him (Jeremiah 29:13, Matthew 7:7-8). God will see to it that those who want to know Him will find the information they need to know to accept Jesus. He can send missionaries or a radio broadcast or a Bible or any number of other messengers to give people the knowledge of how to accept Christ.
