John 3:16

Here our Lord openeth the instrumental cause of justification and salvation, that is, believing εις αυτον, It is one thing to believe in him as a teacher, another thing to believe in him as a Saviour. The object of the first is a proposition; we believe a person when we assent and give credit to what he saith, because he saith it. The object of the latter is the person and merits of the Mediator. As the looking up to the brazen serpent healed the person, not by any physical operation, but from the goodness of God, as it was an act of obedience to the Divine institution for that end; so neither doth faith in the Mediator justify and obtain pardon for any soul from any meritorious virtue in that act, but from God’s gracious ordination, that so it shall be; he hath so ordained, that whosoever shall rest upon Christ, and receive him by faith as his Mediator and Saviour, should not perish, but live for ever. There are other things besides faith necessary to salvation, such are repentance, love, and new obedience; nor is faith only mentioned because they are ingredients into it, but because faith is the root of all those, and that from which they must necessarily flow; for it is as impossible that any should truly hope, and trust in, and rest upon Christ for that life which he hath only promised to those that obey him, as it is impossible that any should indeed trust in and rest upon a man who hath promised a reward upon a condition for that reward, without any care to fulfil that condition. But by this and other places, where faith alone in Christ is mentioned as necessary to salvation. Nicodemus was taught, that no obedience to the works of the law without this faith in the Mediator would bring the soul to eternal life and salvation.

First, Here is God's love in giving his Son for the world (v. 16), where we have three things:— 1. The great gospel mystery revealed: God so loved the world that he gave his only-begotten Son. The love of God the Father is the original of our regeneration by the Spirit and our reconciliation by the lifting up of the Son. Note, (1.) Jesus Christ is the only-begotten Son of God. This magnifies his love in giving him for us, in giving him to us; now know we that he loves us, when he has given his only-begotten Son for us, which expresses not only his dignity in himself, but his dearness to his Father; he was always his delight. (2.) In order to the redemption and salvation of man, it pleased God to give his only-begotten Son. He not only sent him into the world with full and ample power to negotiate a peace between heaven and earth, but he gave him, that is, he gave him up to suffer and die for us, as the great propitiation or expiatory sacrifice. It comes in here as a reason why he must be lifted up; for so it was determined and designed by the Father, who gave him for this purpose, and prepared him a body in order to it. His enemies could not have taken him if his Father had not given him. Though he was not yet crucified, yet in the determinate counsel of God he was given up, Acts 2 23. Nay, further, God has given him, that is, he has made an offer of him, to all, and given him to all true believers, to all the intents and purposes of the new covenant. He has given him to be our prophet, a witness to the people, the high priest of our profession, to be our peace, to be head of the church and head over all things to the church, to be to us all we need. (3.) Herein God has commended his love to the world: God so loved the world, so really, so richly. Now his creatures shall see that he loves them, and wishes them well. He so loved the world of fallen man as he did not love that of fallen angels; see Rom 5 8; 1 John 4 10. Behold, and wonder, that the great God should love such a worthless world! That the holy God should love such a wicked world with a love of good will, when he could not look upon it with any complacency. This was a time of love indeed, Ezek 16 6, 8. The Jews vainly conceited that the Messiah should be sent only in love to their nation, and to advance them upon the ruins of their neighbours; but Christ tells them that he came in love to the whole world, Gentiles as well as Jews, 1 John 2 2. Though many of the world of mankind perish, yet God's giving his only-begotten Son was an instance of his love to the whole world, because through him there is a general offer of life and salvation made to all. It is love to the revolted rebellious province to issue out a proclamation of pardon and indemnity to all that will come in, plead it upon their knees, and return to their allegiance. So far God loved the apostate lapsed world that he sent his Son with this fair proposal, that whosoever believes in him, one or other, shall not perish. Salvation has been of the Jews, but now Christ is known as salvation to the ends of the earth, a common salvation. 2. Here is the great gospel duty, and that is to believe in Jesus Christ (Whom God has thus given, given for us, given to us), to accept the gift, and answer the intention of the giver. We must yield an unfeigned assent and consent to the record God hath given in his word concerning his Son. God having given him to us to be our prophet, priest, and king, we must give up ourselves to be ruled, and taught, and saved by him. 3. Here is the great gospel benefit: That whosoever believes in Christ shall not perish. This he had said before, and here repeats it. It is the unspeakable happiness of all true believers, for which they are eternally indebted to Christ, (1.) That they are saved from the miseries of hell, delivered from going down to the pit; they shall not perish. God has taken away their sin, they shall not die; a pardon is purchased, and so the attainder is reversed. (2.) They are entitled to the joys of heaven: they shall have everlasting life. The convicted traitor is not only pardoned, but preferred, and made a favourite, and treated as one whom the King of kings delights to honour. Out of prison he comes to reign, Eccl 4 14. If believers, then children; and, if children, then heirs.

Give his only begotten Son—God sent not his Son into the world. He was then his Son, his only begotten Son, before he sent him into the world. He was not, therefore, his Son, only by the incarnation, but was his Son from the beginning, as he was also his word from all eternity. This was the constant doctrine of the Church, and of the Fathers, against the heresy of the Arians, that God was always Father,[1] and the Son always the eternal Son of the eternal Father. See note on chap. i. ver. 14. (Witham) — The world may be saved. Why, says St. Augustine, is Christ called the Saviour of the world, unless from the obligation he took upon himself at his birth? He has come like a good physician, effectually to save mankind. The man, therefore, destroys himself, who refuses to follow the prescriptions of his physician. (St. Augustine)

3. Christ here discourses of the great design of his own coming into the world, and the happiness of those that believe in him, v. 14-18. Here we have the very marrow and quintessence of the whole gospel, that faithful saying (1 Tim 1 15), that Jesus Christ came to seek and to save the children of men from death, and recover them to life. Now sinners are dead men upon a twofold account:— (1.) As one that is mortally wounded, or sick of an incurable disease, is said to be a dead man, for he is dying; and so Christ came to save us, by healing us, as the brazen serpent healed the Israelites, v. 14, 15. (2.) As one that is justly condemned to die for an unpardonable crime is a dead man, he is dead in law; and, in reference to this part of our danger, Christ came to save as a prince or judge, publishing an act of indemnity, or general pardon, under certain provisos; this saving here is opposed to condemning, v. 16-18.
