When Jesus spoke to the woman at the well, in John chapter 4 He said that the Samaritans didn't know what they worshipped. (John 4:22) This is true of all the religions of the world. They are in ignorance as the true nature of the God who revealed Himself to Moses. Paul said this in Acts 17:23 when He said that the Athenians were in ignorance. We are even told in 1 Corinthians 10:20 that the Gentiles sacrifice to demons and not to God, while Scripture narrows it even further: "Whoever transgresses and does not abide in the doctrine of Christ does not have God."(2 John 1:9) That's why we must take them to Mount Sinai, let the thunder of the Law strip sinners of selfrighteousness, and bring them to the foot of Calvary's cross. And how shall they hear without a preacher? There goes another minute. Gone forever. Go share your faith while you still have time.
