Michael - Jesus

Why do I call Jesus "Michael"? Because the Bible does. Daniel 10:13, 21 and 12:1; Jude 1:9 and Revelation 12:7 are the only texts that mention "Michael" in this context. If you study these texts carefully you will find that they are all in reference to heavenly places or heavenly beings. Lucifer, having been a heavenly being, would have known Jesus by His heavenly name, "Michael".  In the New Testament, the two references where He is called Michael have to do with His heavenly duty, not earthly duty.

So in Heaven, He was known as Michael. On earth, in the Old Testament, He was known as "YHWH" ( Exodus 6:2, 3); and in the New Testament as Jesus (Luke 1:31).
