"Son of man" refers to Jesus’ humanity - He was born of a woman. 

"Son of God" refers to Jesus' spirituality - He is the Father revealed in flesh.

For in Christ lives all the fullness of God in a human body.

"For it pleased the Father that in him should all fulness dwell;" - Colossians 1:19 KJV

"Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. For in him dwelleth all the fulness of the Godhead bodily." - Colossians 2:8-9 KJV

As a man, He was hungry, tired, thirsty, and prayed.

As God, He multiplied the fish and loaves, healed the sick, raised the dead, and answered prayers.

(When Jesus prayed, it was His flesh praying to the Spirit that is not only within Him, but also is everywhere in the universe.)

The flesh of Jesus died on the tree.

The Spirit of Jesus raised His flesh out of the grave.

Ten days after Jesus ascended up into heaven, He poured out His Spirit on those praying in an upper room on the holy day of Pentecost.

Jesus promises His Holy Spirit to all those that turn away from sin, and make a covenant with Him by being baptized in His name, the name “Jesus.”

"And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: and that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. And ye are witnesses of these things. And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high." - Luke 24:46-49 KJV

Peter preached repentance and remission of sins in Jesus name and the promise of the Holy Ghost to the Jews from all nations that had gathered that were in Jerusalem for Pentecost.

"Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call." - Acts 2:38-39 KJV

All our sins are washed away to start with a “clean slate,” walking with Jesus with a new life!
