Sons Of God

Luke 3:23 (ESV Strong's)

The Genealogy of Jesus Christ

Jesus, when he began his ministry, was about thirty years of age, being the son (as was supposed) of Joseph, the son of Heli,

Luke 3:38 (ESV Strong's)

the son of Enos, the son of Seth, the son of Adam, the son of God.

Adam was created, but was not born a man. He was the son of God. 

Jesus was born a man, but was not created. He is the Son of God. 

We are born of man, then reborn from above. We are sons of God.
