The Bible is clear about Jesus being the only way of salvation. He's the only way to have your sins forgiven and attain eternal life.
Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me." John 14:6
"Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved." Acts 4:12
Yet, there are people on this planet who have never heard of Jesus. Let's use an example of a native African who lives deep in the jungle who is removed from communication with the rest of the world. This individual will die and face judgment, never having heard the gospel message of forgiveness of sins. Will God find him guilty of breaking His laws and punish him accordingly? How is it fair for God to condemn him to hell never having an opportunity to receive Jesus as his savior?
Let's ask the question, why does an individual go to hell? The answer is not because they haven't received Jesus as their savior, but because they've sinned against God. Everyone who goes to hell goes there simply because of their sins. This is an important distinction to make. People who go to heaven, go because of God's grace, people who go to hell, go because of their own sins. We know that the native African has broken God's laws, "For all have sinned and fall short of the glory of God." Romans 3:23 He, therefore, will end up in hell if he doesn't receive forgiveness for his sins. The argument is, "He never had the opportunity for forgiveness!"
Let's examine that in light of Scripture. First off, the Bible declares that every single person knows that God exists. We know this because we see all that He has made. We see His creation, the universe, and everything that surrounds us.
"What may be known about God is plain to them, because God has made it plain to them. For since the creation of the world, God's invisible qualities-his eternal power and divine nature-have been clearly seen, being understood from what has been made, so that men are without excuse." Romans 1:19,20
They are without excuse. Additionally, even primitive tribes have a concept of right and wrong. This is evidence by the false gods and false religious systems they have in place. Prayers and sacrifices are made to these idols in an attempt to appease this god or gods. Although they don't have the written law of God as revealed in the Bible, God gave them an innate sense of right and wrong, and a conscience has been given to every human being. God gave this to every person, Jew and Gentile alike, as well as to the civilized and uncivilized.
Romans chapter 2 states, "All who sin apart from the law will also perish apart from the law, and all who sin under the law will be judged by the law. For it is not those who hear the law who are righteous in God's sight, but it is those who obey the law who will be declared righteous. Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law, since they show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts now accusing, now even defending them. This will take place on the day when God will judge men's secrets through Jesus Christ, as my gospel declares." Romans 2:12-16
The fact is that all people are accountable to God. The problem is that most people reject what has been revealed to them. Back to Romans chapter 1, "For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles. Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another. They exchanged the truth of God for a lie, and worshiped and served created things rather than the Creator-who is forever praised. Amen." Romans 1:21-25
If the native in Africa would respond to the light he has been given, it's my belief that God will get him the gospel of Jesus Christ somehow. Deuteronomy 4:29 proclaims, "But if from there you seek the LORD your God, you will find him if you look for him with all your heart and with all your soul."
Everyone who truly seeks after God will find Him. If a person truly desires to know God, God will make Himself known. God will send a missionary. God will get a Bible into his hand. God will arrange for him to hear the truth of the gospel. Again, the problem is most don't respond to what has already been given to them.
If they have rejected creation, inner light and conscience what makes us think they would respond to further revelation?
Yet, we know that some will respond and therefore we are commanded to go. Because we, as Christians, are the means that God uses to draw those people to Himself. Further in the book of Romans we read, "Everyone who calls on the name of the Lord will be saved. How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? And how can they preach unless they are sent? As it is written, "How beautiful are the feet of those who bring good news!" Romans 10:13-15
It's ironic that everyone who raises the question, "What happens to the person who has never heard about Jesus?", has heard about Jesus, and is currently rejecting Him. The Bibles teaches that there are degrees of severity in terms of punishment in hell. It will be more unbearable for the one who has heard of Christ and rejected Him, than the one who has received less light. This should terrify those who know the truth and yet remain in rebellion. Please, if have spent any time at all on this website, you know the offer of total forgiveness of your sins through the death of Jesus Christ. You are absolutely without excuse. Please don't reject this offer, repent and put your faith in Christ today.
