John 10:36

Sanctified; set apart to the office of the Redeemer of lost men.

Sent into the world; to do the work of the Messiah.

Because I said, I am the Son of God; the argument is from the less to the greater: If mere men were called gods because the word of God came to them, how much more may he who is one with the Father, and whom the Father has set apart and sent into the world as the Saviour of men, call himself the Son of God. He goes on to show that his works justify him in taking to himself this title.
