Immediately after saying “You are my Son, today I have begotten you” (Ps. 2:7), God indwelt the body of His Son, resulting in the union of two distinct personalities in one body, the Father as pure spirit and the Son an angelic being. I call this union “Theosomatic,” from two Greek words “Theos” (God) and “Soma” (Body). The Body belongs to the Son while the divine spirit belongs to God the Father.
God’s indwelling in the Son does not mean, however, that the full person of God is in the Son as God is omnipresent to be everywhere. It simply means that His full authority and power is in the Son. In the words of Apostle Paul, “in Him, all fullness of Deity dwells in bodily form” (Colossians 2:9). It is clear that the Son’s full powers are not His own but of the indwelling Father. On the other hand, John the Baptist says that the Son “receives the Spirit without measure, as the Father loves the Son, and has given all things into His hand” (John 3:34-35).
As the Word of God from the very beginning, the Son can now speak the words of the indwelling Father. What the Father dictates, the Son speaks. In other words, the Son becomes the mouthpiece or spokesman of the voiceless Father. And because the angelic body can be visible or invisible, the Son is then described as the “image” of the invisible God (Col. 1:15).
