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."
To see life is here put for “enjoying life.” But to express more clearly that no hope remains for us, unless we are delivered by Christ, he says that the wrath of God abideth on unbelievers. Though I am not dissatisfied with the view given by Augustine, that John the Baptist used the word abideth, in order to inform us that, from the womb we were appointed to death, because we are all born the children of wrath, (Ephesians 2:3.) At least, I willingly admit an allusion of this sort, provided we hold the true and simple meaning to be what I have stated, that death hangs over all unbelievers, and keeps them oppressed and overwhelmed in such a manner that they can never escape. And, indeed, though already the reprobate are naturally condemned, yet by their unbelief they draw down on themselves a new death. And it is for this purpose that the power of binding was given to the ministers of the gospel; for it is a just vengeance on the obstinacy of men, that they who shake off the salutary yoke of God should bind themselves with the chains of death.
