The Son of God and the Son of Man
The two titles have two different meanings for the same person and have to do with the office of the person before entering time and after entering time.
The Son of God is a title given to us for the One and only Son proceeding from the Father who in eternity past existed in complete unity with the Father as part of the Trinitarian God head as revealed in scripture.
The Son of man is a title given to Jesus of Nazareth who claimed the name for himself while displaying that He was also the Son of God and the Christ; and that not without signs and wonders. This title should produce a close look at the scriptures because it has some serious logical conclusions built into it. The Son of man implies that one is born of man. Man here could be looked at in a universal form, as in ‘human race’ or ‘mankind’. Christ’s resurrection from the dead is relevant to this discussion;
“But now Christ has been raised from the dead, the first fruits of those who are asleep. For since by a man came death, by a man also came the resurrection of the dead.” (1 Corinthians 15:20-21 NASB)
The Son of God entered into time and took on full humanity in order to fulfill what fallen man alone cannot; fulfill the Holy commands of God in perfection and worship and enjoy Him above all else. His perfect obedience and worship solidifies Him as who He claimed to be, the Son of God, the Christ, and the spotless lamb of God slain for His chosen people.
The son of man is the firstborn from the dead; Christ is the firstborn from among us and we too will rise! What is sown perishable will be raised imperishable. A seed doesn’t burst forth until it is planted and dies, God gives it a new body by His power. Kiss the Son, for He has brought us a true and living hope!
