Where Did Satan Come From?

QUESTION: Where did Satan come from?

ANSWER: From himself. As a sinless creature God created him, but as a devil he made himself (Isaiah 14:12; Luke 7:18, John 8:44, II Peter 2:4; Jude 6; Rev. 12:3). Dr. Bushnell and others, myself included, think that a scheme of redemption was provided which some angels accepted and became confrmed in holiness, and others rejected and became permanently fixed in wickedness.
