John 3:36

“He that believeth on the Son, etc.] Who is a proper object of faith and trust; which, if he was not truly and properly God, he would not be: and this is to be understood not of any sort of faith, a temporary, or an historical one; but of that which is the faith of God’s elect, the gift of God, and the operation of his Spirit; by which a man sees the Son, goes unto him, ventures and relies upon him, and commits himself to him, and expects life and salvation from him; and who shall not be ashamed and confounded; for such an one hath everlasting life; he has it in Christ his head, in whom he believes; he has a right unto it through the justifying righteousness of Christ, and a meetness for it…”

“hath everlasting life--already has it. (See on Joh 3:18 and Joh 5:24). shall not see life--The contrast here is striking: The one has already a life that will endure for ever--the other not only has it not now, but shall never have it--never see it. abideth on him--It was on Him before, and not being removed in the only possible way, by "believing on the Son," it necessarily remaineth on him!

Next: John Chapter 4”

“Hath everlasting life - Has or is in possession of that which is a recovery from spiritual death, and which will result in eternal life in heaven. Piety here is the same that it will be there, except that it will be expanded, matured, purified, made more glorious. It is here life begun the first breathings and pantings of the soul for immortality; yet it is life, though at first feeble and faint, which is eternal in its nature, and which shall be matured in the full and perfect bliss of heaven. The Christian here has a foretaste of the world of glory, and enjoys the same kind of felicity, though not the same degree, that he will there. Shall not see life - Shall neither enjoy true life or…”

“He that believeth on the Son hath everlasting life - He hath it already. For he loves God. And love is the essence of heaven. He that obeyeth not - A consequence of not believing. Next: John Chapter 4”

“3:36 God gave the gift of eternal life, promising new life and intimacy in a present experience with God. • Those who reject the Son will not see life. The world in its darkness stands under God’s angry judgment (Rom 1–3).”
