At Revelation 12:7 we learn that "Michael and his angels" fight a vital war that results in the ousting of Satan the Devil and his wicked angels from heaven.
Revelation, likewise, describes Jesus as the Leader of an army of faithful angels. (Revelation 19:14-16) And the apostle Paul specifically mentions “the Lord Jesus” and “his powerful angels.” (2 Thessalonians 1:7; Matthew 16:27; 24:31; 1 Peter 3:22)
So the Bible speaks of both Michael and “his angels” and Jesus and “his angels.” (Matthew 13:41)
These facts leave us with a series of fascinating questions:
1. Who is Michael?
2. Who are his angels?
3. Why did he lead the war against Satan instead of Christ?
4. Are there two separate groups of loyal angels, one belonging to Christ and another to Michael?
