Will all those people who have never heard of Jesus Christ be sent to hell? First we must note that the Bible says God will judge all people righteously. It seems there will be a stricter judgment for those who have rejected the gospel of Jesus Christ than those who have never heard.Paul tells us that those who have never heard of the law are not imputed sin under the law. Paul also tells us that those who follow the law (e.g., practicing Jews) will be judged by the law. The people who have never heard of the law are judged by the law of God which He has placed into their hearts:
For when Gentiles who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves, in that they show the work of the Law written in their hearts, their conscience bearing witness, and their thoughts alternately accusing or else defending them, on the day when, according to my gospel, God will judge the secrets of men through Christ Jesus. Romans 2 :14 -16
I know there are many Christians who say that all those who die without faith in Christ will be relegated to spend eternity in Hell - even if they have never heard the gospel. I think scripture suggests otherwise - that we are judged on the basis of what we know and how we act upon it. This is not any sort of ecumenical theology or "all ways lead to God." Those who have heard the gospel of Jesus Christ and have refused to believe have rejected Him, and, as such, will fall under the condemnation of God, because they have rejected His provision for our disobedience.Therefore, atheists are still without excuse in rejecting God. Those who perpetrate evil, even without the knowledge of the gospel, will likewise be condemned, since they have violated their God-given conscience. In the same way, those who play the "religion game" of going to church on Sunday, but living apart from a relationship with God, will be condemned.
