Christians are often confronted with a question that is hard to answer. It is a difficult question, not because it challenges our faith in Jesus Christ; that he sealed a new Covenant with God by taking on the sins of the world, but because of our genuine desire that all should find redemption, and be justified when it is their time to stand before God.
In fact, that is our charge given by Jesus himself just prior to his ascension. Mark 16:15 tells us, “He said to them, Go into all the world and preach the good news to all creation.” As an aside, I might take this opportunity to point out that Jesus did not tell his followers to kill the infidels if they refuse to believe, as some “peaceful” religions are known to do.
Nevertheless, we know that in John 14:6, “Jesus answered, I am the way and the truth and the life. No one comes to the Father except through me.” This seems to be an ominous declaration, but tempered by God’s assurance. John 3:16 says, “God so loved the world, that He gave his only begotten Son; that whoever believes in Him shall not perish, but shall have eternal life.”
So you see that the question Christians are often confounded with is, “Well, what about the people in the far corners of the Earth, who have never heard of Jesus?” This makes us take a deep breath and ponder, because we do not want to believe that God would just leave people out, through no fault of their own.
This troubles us, even though we can step back and understand that God cannot be judged as we might judge people. After all, God created all that there is. He owns everything, including every creature human or otherwise that ever existed. He is the Alpha and the Omega, the Beginning and the End. Nothing exists outside of God. To try to judge God on some human threshold is like being fit to be tied because we are forced to breathe air.
There is another angle to this; however, I am not well enough educated in the Scriptures to declare this as the Gospel Truth, though it seems reasonable. You should read the entire article at the following link, but in a nutshell, it is saying that God’s law is written on everyone’s heart (the conscience if you will).
The Scriptures seem to indicate that judgment will be harsher for those who have heard the truth, but choose to turn away from it. In other words, those who know of Jesus, but refuse to believe. Those who have never heard of Jesus or of any of God’s written law (as the Jews have had) still have that natural law of good and evil written in their hearts. Those who choose evil, while knowing the good, shall be judged just as harshly.
