Jesus' favorite term for Himself was the "Son of Man".
Jesus had to become Man.
- To perfectly fulfill the Law of God
- To live a sinless life so that He would be the perfect sacrifice for sin
- To die on the cross in the place of every single man, woman, boy, and girl that would ever inhabit this planet.
- To suffer the punishment that we rightfully deserve as the penalty for our sins
- To defeat sin, Satan, death, and hell
- To be our high priest
Because God became one of us, He understands us, can relate to us, and can better minister to us.
Hebrews 2:18 Because He himself suffered when he was tempted, he is able to help those who are being tempted.
The purpose of the Incarnation was for God to identify Himself with mankind.
