[Christ's] human nature, after the resurrection from the dead, is exalted above all creatures in heaven and on earth. This is nothing other than that He entirely laid aside the form of a servant. He did not lay aside His human nature, but retains it to eternity. He has the full possession and use of the divine majesty according to His received human nature. However, He had this majesty immediately at His conception, even in His mother's womb. As the apostle testifies, He laid it aside. Dr. Luther explains, He kept it concealed in the state of His humiliation and did not always use it, but only when He wanted to use it.
Now He has ascended to heaven, not merely as any other saint but above all heavens. He also truly fills all things, being present everywhere, not only as God, but also as man. He rules from sea to sea and to the ends of the earth, as the prophets predict [Psalm 8:1, 6; 93:1-4; Zechariah 9:10] and the apostles testify. He did this everywhere with them and confirmed their word with signs. This did not happen in an earthly way. As Dr. Luther explains, this happened according to the way things are done at God's right hand. "God's right hand" is no set place in heaven. It is nothing other than God's almighty power, which fills heaven and earth. Christ is installed according to His humanity without confusing or equalizing the two natures. (paragraphs 26-28)
