Behold, you will conceive in your womb and bring forth a Son, and shall call his name Jesus. ... The Holy Spirit will come upon you, and the power of the Highest will overshadow you; therefore, also, that Holy One who is to be born will be called the Son of God.
(Luke 1, 31.35)
Holy Scripture places just as much definite emphasis on the true manhood of Jesus Christ as it does on His being the Son of God. Entering this earth, He became "flesh" or Man (John 1,14; 1 Timothy 2, 5). Yet He remained God. God and Man in one Person is a mystery that exceeds our comprehension, as does the Trinity.
The incarnation of the Son of God was a necessary aspect of God's counsel, so that sinners could be saved from condemnation. All humans have sinned (Romans 3, 23) and so that they might escape God's just punishment, a human being had to become their substitute. That substitute had to be guiltless, pure and holy.
None other than the Son of God could take on this part, for everyone was tainted with sin by descent (Job 14, 4). However, when the Son of God became Man, having been conceived by the virgin Mary through the intervention of the Holy Spirit, He was born spotless. He was the "Holy One". So in His human nature, too, He was absolutely sinless and holy. In addition, He was the Son of God as Man.
Jesus Christ the righteous suffered death for the unrighteous, so that we might live through Him (1 Peter 3, 18). The Word of God does not present the Son of God for us to attempt to analyse His Person, but for us to accept Him by faith and worship Him.
