He who believes in him is not judged. He who doesn't believe has been judged already, because he has not believed in the name of the one and only Son of God.
because he hath not believed in the name of the only begotten Son of God; whom God has sent to be the Saviour of lost sinners, and to deliver them from wrath to come; and there is no other name but his, whereby men can be saved; so that such that do not believe in him, must be damned.
