Who was the fallen angel that became Satan?

Answer 1

Yes. The name of satan (adversary of man) before his fall was Lucifer (heylel

light-bearer, son of morning). The account of the fall of Lucifer is found in Isaiah 14:12-20. In eternity past, we do not know exactly when this occurred, Lucifer deceived 1/3 of the righteous angels to attempt usurp the Authority of the Almighty GOD. The revolt of course failed because the created cannot defeat the Creator. GOD cast the fallen angels out of Heaven, but they are still subject to GOD, Job chapters 1&2. This "mystery" displays the height, breadth, and length of the Love of GOD (Romans 8:39) that HE did not destroy these rebellious angels but has allowed them to exist in excess of 7 millennia. Their day of judgment is coming (Revelation 20:11-15), when they, death, and hell are cast into the Lake of Fire. This judgment is not based on vengeance but the Justice of GOD. In fact if the fallen angels had not blasphemed the Holy Spirit, the only unforgivable sin, Matthew 12:31, GOD would have restored them because GOD is in the Business of Restoration. However, the fallen angels did blaspheme the Holy Spirit and furthermore, they do not believe the Word of GOD, and they believe that they can still defeat the GOD of Wonders; such is the depravity, delusion, and insanity of sin.
