This is the question of the collegecampuses, the skeptic and the agnostic. This is the question of those who wish todeflect making a personal commitment to Christ. This is the question of those wholike to play mental gymnastics with God. This is just my opinion, but here is how I would approach the question.

Acts 10 gives us a beautiful story of a God-fearing man names Cornelius. He was a good and righteous man who had never heard of Jesus Christ, but believed in God. Cornelius was praying to God when God sent him a vision to send for Peter. At the same time, God sent a vision to Peter to go with the men that were sent for him. When Peter met Cornelius, Peter told him of Jesus and Cornelius was saved.
