I've never heard this discussed much among Christians. Any ideas on why Satan was able to convince some of God's angels to join him in his rebellion against God? I realize anything we come up with is pure speculation on our part. The Bible never directly discusses this situation. However, I've recently come across something in scripture that gives me a place to start with. In the book of Hebrews 1:5, it says, "God never said to any of His angels, 'You are my Son. Today I have become your Father.' And God never said to any of his angels, 'I will be his Father, and he will be my Son.' " In Hebrews 1:14, it says, "What are all the angels? They are spirits sent to serve those who are going to receive salvation." Maybe the angels felt rejected by God. After all, it appears the Bible teaches that God loved mankind but not the angels. They were merely "servants" that were to do God's bidding. Maybe that sense of rejection turned into resentment. Maybe Satan tapped into that and convinced the angels that they should turn their back on God since they didn't mattter to Him. Satan possibly looked like a liberator to these angels. Like he had their best interests at heart. That then increased their sense of loyalty to Satan. Which then made it easier for them to join Satan in his rebellion and seal their fate.
