Numbers 23:19 “God is not a man…nor a son of man…”
The Bible often calls Jesus “a son of man” or “the son of man.”
Matthew 12:40 “…so will the son of man be…”
Matthew 16:27 “For the son of man is going to come…”
Matthew 28 “…until they see the son of man coming in His kingdom.”
Mark 2:10 “But so that you may know that the Son of Man has authority…”
John 5:27 “…because He is the son of man.”
In the Hebrew Scriptures, the “son of man” is also used many times speaking of people (Job 25:6; Psalm 80:17; 144:3; Ezekiel 2:1; 2:3; 2:6; 2:8; 3:1; 3:3; 3:4; 3:10; 3:17; 3:25.(
Since God would not contradict Himself by first saying He is not the son of a man, then becoming a human being who was called “the son of man”, he would not have done so.
Remember God is not the author of confusion. Also, human beings, including Jesus, are called “son of man” specifically to distinguish them from God, who is not a “son of man” according to the Bible.
