What is the difference between “the son of man” and “the son of God”?
Jesus is both the Son of Man and the Son of God. We see that the Son of Man is Jesus in Luke 12:8-9.
8 “I tell you, whoever publicly acknowledges me before others, the Son of Man will also acknowledge before the angels of God. 9 But whoever disowns me before others will be disowned before the angels of God.
We see that Jesus is the Messiah, who is the Son of God in John 20:31.
But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.
The Jews wanted to kill Jesus in part because by calling himself the Son of God, He was making Himself equal to God. John 5:18
18 For this reason they tried all the more to kill him; not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God.
When He called Himself the son of Man, he was probably referring to Daniel 7:13-14
13 “In my vision at night I looked, and there before me was one like a son of man, coming with the clouds of heaven. He approached the Ancient of Days and was led into his presence. 14 He was given authority, glory and sovereign power; all nations and peoples of every language worshiped him. His dominion is an everlasting dominion that will not pass away, and his kingdom is one that will never be destroyed.
These terms speak of Jesus’ humanity (Son of Man), and His deity (Son of God). These speak to the dual nature of Jesus Christ, 100% man and 100% God.
