In the holy gospel, I see that Jesus is called as"son of man" in some occasions, whereas "son of God" in some other. By normal thinking it could be concluded that both are statements of contradictions. What would have been really meant by these names? and How do they target the same man, though it seems different in meaning?
Jesus is the Son of God. He is often called the son of man to tell people that He is the coming messiah that everyone needs. How can calling Him the son of man tell people he's the messiah? Enter Daniel 7:13:
“I saw in the night visions, and behold, with the clouds of heaven there came one like a son of man, and he came to the Ancient of Days and was presented before him.
This was Old Testament prophecy from the prophet Daniel where he saw Jesus Christ, who came from the clouds of heaven like a "son of man".
People knew the Old Testament pretty well at the time, so when Jesus was referenced as the son of man, people immediately recollected Daniel's vision and connected the dots, placing Jesus as the messiah. Pretty cool, eh?
Your question goes to the basic belief of the Southern Baptist belief in that we believe that Jesus was wholly man and wholly God.
When Jesus was referred to as the son of man (usually by himself) he was making reference to his human which he inherited through Mary his human mother.
Luke 1:35 KJV And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.
When he was referred to as the son of God it is in reference to his Deity which He inherited through the Holy Spirit.
In Luke 1:35 we are informed that the Birth of Jesus was a result of Mary being pregnant through the Holy Ghost, by the Power of the highest.
With this we are informed that Mary became pregnant by what can be referred to as artificial insemination for lack of a better term.
This was in keeping with Isaiah's prophesy in:
Isaiah 7:14 KJV Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.
This concept has met with much controversy, even in view of the fact that it is possible through a medical procedure today.
