Although the titles of Son of God and Son of Man in the Messianic context point to the same Entity, their roles and purpose are very defined and for good reasons. His being The Son of God came about from His Spiritual Birth when God's Word brought forth, or could even be understood as having become, His own Son. This serves the will and pleasure of God of having One whom He can call as a Son. On the other end, His being the prophesied Son of Man resulted when He was conceived by the Holy Spirit and appeared on earth through a human birth. This serves the love of God towards His special creation, that is of man whom He created in His own image.
