Light Blowing Wind

I've heard from the beginning of my Christian education that Satan/Lucifer was good (some say perfect0, then went bad.

ORLY? What JC have to say about him?

John 8:44 You are of your father the devil, and your will is to do your father's desires. He was a murderer from the beginning, and has nothing to do with the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies.

"Murderer from the beginning"?

II Cor. 11:14

14 And no wonder, for even Satan disguises himself as an angel of light.

Great googly-moogly! Satan, an archangel of light himself, disguises himself as an angel of light. Why in the world would he need to make himself into something he already is?

The very definition of Satan, meaning "adversay", tells us exactly who he is and what he was created for; namely that he may "SIFT you as wheat" (Luke 22:31).

Paul reiterates:

"To deliver such an one UNTO SATAN for DESTRUCTION of the flesh, that the spirit may be saved in the day of the Lord Jesus" (I Cor. 5:4-5)"

We must be willing to believe that which we know isn't so in order to understand the truth.
