Colossians 1:15 Who is the image of the invisible God, the firstborn of every creature
With these facts it is clear in what sense Jesus is “the firstborn of every creature” or of all creation (1:15), and “the firstborn among many brethren” (Rom. 8:29). All creation came into existence by creative acts, not by a begetting as in the case of Jesus. Even the “many brethren” are not begotten in the sense Jesus was by the Holy Spirit. They were begotten by people, not by God, and were thus brought into the human family, not the family of God. The only way one gets into God’s family is by adoption (Rom. 8:14-16; Gal. 4:5-6; Eph. 1:5). Jesus is the only begotten Son … the first of all creatures to be begotten of God, the only one of all beings begotten of God, the first and only one of the family of adopted and “created” brethren begotten of God (Eph. 4:24; Col. 3:10), the first begotten of or from the dead, and the firstfruit of the resurrection of all men (1:18; 1Cor. 15:23-33; Rev. 1:5). The body of Christ (consisting of all Christian congregations) is the called-out people of the one who is the firstborn (Heb. 12:23). Adam and angels were by creation, not by begetting (Luke 3:38; Gen. 6:1-4; Job 1:6; 38:4-7).
This refers to the incarnation when the second person of the Divine Trinity took a human body to redeem (Php. 2:5-11; Isa. 7:14; 9:6). It was when God had a Son through Mary (Matt. 1:18-25; Luke 1:35; John 1:14). This happened on a certain day: “This day have I begotten thee” (Heb. 1:5-7). Therefore, we cannot say that God had a Son before this time. This proves that sonship in connection with God had to refer to humanity and not to deity.
