"And he will destroy in this mountain the face of the covering cast over all people, and the vail that is spread over all nations." Isaiah 25:7
Many people feel that every nation should be encouraged simply to practice its own religion. God's Word, however, makes it plain that all nations are blinded, cut off from the truth by a deadly covering. This is true of the Jews, for "even unto this day, when Moses is read, the vail is upon their heart" 2 Corinthians 3:15.
It is also true of the Gentiles, who have "the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart" Ephesians 4:18.
The veil that keeps them in such darkness is a Satanic blindfold. "The god of this world i.e., Satan hath blinded the minds of them which believe not" 2 Corinthians 4:4.
And how did the devil ever gain such control over human minds? "Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. . . . Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator" Romans 1:21, 25.
So today, men and women almost everywhere--atheists, Communists, humanists, Buddhists, Confucianists, animists, Hindus, Taoists, Shintoists, occultists, "New Agers," and even the "liberals" in the monotheistic religions (Judaism, Islam, Christianity)--really all believe and practice the same religion, rejecting God as Creator and worshipping instead some man or man-exalting evolutionary philosophy.
Someday, God will destroy this pervasive veil over the nations. In the meantime, we must reach everyone we can with the true and everlasting gospel of Christ, for that "vail is done away in Christ" 2 Corinthians 3:14
