The Son of God is very and eternal God (e.g. John 1:1; 20:28; Rom. 9:5). He is God from all eternity. He is one substance and equal with (Phil. 2:6; John 5:18) God the Father and the Holy Spirit (see Chapter 2). He made the world (John 1:3) and furthermore, He upholdeth and governeth all things he hath made (Heb. 1:3). He does not only create, but also preserve all that He has made and lead them to their predetermined end. This eternal and blessed God, when the fullness of time was come (Gal. 4:4), took upon Him man's nature (Phil. 2:6-7; Heb. 2:14; 4:15). This is the miracle and wonder of the Incarnation. He truly became man and was not half man and half God. He took human nature with all the essential properties and common infirmities thereof, except for sin (Heb. 4:15), for that is not an essential property of human nature (Heb. 2:14). Sin is a distortion of human nature as it was created by God. He took upon Himself all things which make humans human and including our limitations. These things were perfectly present in the Lord Jesus Who is God and man.
The Lord Jesus in His nature was conceived by the Holy Spirit in the womb of the Virgin Mary (Luke 1:35). His human life had a beginning in time 2000 years ago. But His divine nature is without beginning. Furthermore, His conception was not a human work, but a divine miracle by the Holy Spirit. He was not born by “ordinary generation” (chapter 6:3). In this way, the promise of the Protoevangelium was fulfilled in the birth of the seed of the woman (Gen. 3:15). He was from Judah (Gen. 49:10), of the seed of Abraham (Gen. 12:3; 22:18; Gal. 3:16) and David (2Sam. 7:12-16; Rom. 1:3), as the Scriptures promised and taught. His divine nature, as well as His human nature, is perfect. They are distinct and inseparably joined together in one person. Jesus does not have a divine person and a human person. Rather, He is one person with two distinct natures. Then the Confession goes on to explain what this joining of the two distinct natures is not. It is not the conversion of one nature to something else. It is not the composition (adding, combining) of two natures into one, thus creating something new. Nor is it the confusion (fusing, mixing) of the natures. The Lord Jesus is one person Who is very God and very man. He is truly God and truly man. Nonetheless, there is but one Christ. There is not a human Christ and a divine Christ. There is only one Christ Who is both divine and human. Therefore, He is the only mediator between God and man (1Tim. 2:5), being able to represent both parties.
The Son of God, Eternal God
The Son of God is God from all eternity, in and of Himself. His deity is not derived or dependent upon the Father or the Spirit. Each Person of the blessed Trinity is divine in and of Himself. The Son has been God forever, see for example John 1:1, 14; 17:5; Isaiah 9:6. See also our discussion of the Trinity in Chapter 2 of the Confession.
The Brightness of the Father's glory
The Lord Jesus is the physical representation of God. Truly, to see Him was the same as to see God the Father (John 14:9-10). He is described as the One Who has “exegeted” the Father to us (John 1:18). Hebrews 1:3 describes Him as the “radiance of...
