I don't know...I've never thought about it that way. "God is light"[1 John 1:5] And this is the message that we have heard from Him, and announce to you, that God is light, and darkness in Him is not at all.
It goes without saying that Satan would be the opposite of light.....but, be careful. [2 Corinthians 11:13-14] For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ. And no marvel; for Satan himself is transformed into an angel of light.
Transformed, as used above, can also be disguised. He will be disguised as Christ, coming to deceive. I wonder how many know he will be the "instead of Christ"? How many are prepared for the deception? Christ told us he would be so good at it that (Mk.13:20 & 22)"even the elect could be seduced so He shortened the days".
Rev.8:11 And the name of the star is called Wormwood. He'll be disguised as the Morning Star, Christ - an angel of light.
Rev. 12:9 And the great dragon was cast out, that old serpent, called the Devil and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
Rev. 3:10.Because thou hast kept the word of My patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
Are we ready for that?
