'Son of God' in the Bible

he that commits sin is of the devil, for the devil sinned from the beginning. For this was the Son of God manifested, to destroy the works of the devil.

Whoever confesses that Jesus is the Son of God, God continues in him and he in God.

Who is he that overcomes the world, but he that believes that Jesus is the Son of God?

He that believes on the Son of God has the testimony in himself; he that believes not God has made him a liar, because he has not believed in the testimony which God has testified concerning his Son.

These things have I written to you, that you who believe in the name of the Son of God may know that you have eternal life.

And we know that the Son of God has come, and has given us understanding that we may know the true One; and we are in the true One, in his Son Jesus Christ; this is the true God, and eternal life.
