Jesus lived as a spirit person in heaven before he was born in Bethlehem. He was God’s first creation and the only one created directly by God. Therefore, he is fittingly referred to as God’s only-begotten Son. In heaven, he often spoke as God’s representative. That is why he is called the Word. He also acted as God’s helper and took part in the creation of all other things. (John 1:2, 3, 14) Jesus lived with God in heaven for eons before humankind was created.—Read Micah 5:2; John 17:5.
THE spirit creature called Michael is not mentioned often in the Bible. However, when he is referred to, he is in action. In the book of Daniel, Michael is battling wicked angels; in the letter of Jude, he is disputing with Satan; and in Revelation, he is waging war with the Devil and his demons. By defending Jehovah’s rulership and fighting God’s enemies, Michael lives up to the meaning of his name—“Who Is Like God?”
God’s Word refers to Michael “the archangel.” (Jude 9) This term means “chief angel.” Notice that Michael is called the archangel. This suggests that there is only one such angel. In fact, the term “archangel” occurs in the Bible only in the singular, never in the plural. Moreover, Jesus is linked with the office of archangel. Regarding the resurrected Lord Jesus Christ, 1 Thessalonians 4:16 states: “The Lord himself will descend from heaven with a commanding call, with an archangel’s voice.” Thus the voice of Jesus is described as being that of an archangel. This scripture therefore suggests that Jesus himself is the archangel Michael.
