Christ Jesus declared with all power and intensity: “You are Gods!” […] At the very beginning of man’s evolution, Lucifer proclaimed: “Ye shall be as Gods!” […] From Lucifer this utterance leads to a curse, from Christ to the highest blessing. Is there not a wonderful mystery here? The words hurled into humanity by Lucifer, the Tempter — when uttered by Christ to men are supreme wisdom.
What is really important is not the content of an utterance but from whom it comes; this fact is inscribed in letters of power into the biblical record.
