3:17. For God sent not his Son into the world, to judge the world: but that the world may be saved by him.
3:18. He that believeth in him is not judged. But he that doth not believe is already judged: because he believeth not in the name of the only begotten Son of God.
Is not judged... He that believeth, viz., by a faith working through charity, is not judged, that is, is not condemned; but the obstinate unbeliever is judged, that is, condemned already, by retrenching himself from the society of Christ and his church.
3:19. And this is the judgment: Because the light is come into the world and men loved darkness rather than the light: for their works were evil.
The judgment... That is, the cause of his comdemnation.
3:20. For every one that doth evil hateth the light and cometh not to the light, that his works may not be reproved.
3:21. But he that doth truth cometh to the light, that his works may be made manifest: because they are done in God.
He that doth truth... that is, he that acteth according to truth, which here signifies the Law of God. Thy law is truth. Psa. 118. 142.
3:22. After these things, Jesus and his disciples came into the land of Judea: and there he abode with them and baptized.
3:23. And John also was baptizing in Ennon near Salim: because there was much water there. And they came and were baptized.
