'Son of God' in the Bible

He who is habitually guilty of sin is a child of the Devil, because the Devil has been a sinner from the very beginning. The Son of God appeared for the purpose of undoing the work of the Devil.

Whoever acknowledges that Jesus is the Son of God--God continues in union with him, and he continues in union with God.

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

He who believes in the Son of God has the testimony in his own heart: he who does not believe God has made Him a liar, in that he has refused to accept the testimony which God has given about His Son.

He who has the Son has the Life: he who has not the Son of God has not the Life.

I write all this to you in order that you who believe in the Son of God may know for certain that you already have the Life of the Ages.

And we know that the Son of God has come, and has given us understanding so that we know the true One, and are in union with the true One--that is, we are in union with His Son Jesus Christ. He is the true God and the Life of the Ages.
