As discussed in the LAST TWO POSTS of this series, the “true religion” is the revealed religion, the “preached” religion; it is “the mystery which has been hidden from ages and from generations” and is a religion which “we preach, warning every man and teaching every man in all wisdom” (Col. 1:26,28). And as we will see, it is in fact the revealing and preaching of Jesus Christ Himself, in both Old and New Testaments, for “there is no salvation in any other, for there is no other name under heaven given among men by which we must be saved” (Acts 4:12) and “no one knows the Son except the Father. Nor does anyone know the Father except the Son, and the one to whom the Son wills to reveal Him” (Matt. 11:27).
As such, we must next discuss what exactly “revelation” is. For starters, the Greek word we commonly translate “revelation” is apokalýptō, from the roots apó, “away from” and kalýptō, “to cover.” Literally speaking, it means to take away the cover, revealing what is hidden, veiled, or obstructed, especially the inner concealed make-up. In Greek texts it often means to show forth the unseen, immaterial, deep nature of something—what cannot be known by the senses alone.
