The F.O.G*

[18] Those who believe in Him are not condemned, but those who don't believe are already under condemnation because they have rejected God's one and only Son. Those trusting in Him are not judged, but those who are not trusting in Him have already been judged because they have not trusted in the name of the unique Son of Yahweh.

The F.O.G Paraphrase

he who is believing in him is not judged, but he who is not believing hath been judged already, because he hath not believed in the name of the only begotten Son of God.
