One who believes in the Son has eternal life, but one who disobeys{The same word can be translated "disobeys" or "disbelieves" in this context.} the Son won't see life, but the wrath of God remains on him."
He that cometh from above is above all: he that is of the earth is earthly, and speaketh of the earth: but he that cometh from heaven is above all. And what he hath seen and heard, that is what he testified; and no man received his testimony ( John 3:31-32 ).
