For the Father loveth the Son. Every body sees how harsh and far-fetched is the exposition of this passage which is given by the Fathers. "God," they say, "loves himself in the Son." But this statement applies beautifully to Christ as clothed with flesh, that he is beloved by the Father. What is more, we know that it is by this excellent title that he is distinguished both from angels and from men, This is my beloved Son, (Matthew 3:17.) For we know that Christ was chosen, that the whole love of God might dwell in him, and might flow from him to us as from a full fountain. Christ is loved by the Father, as he is the Head of the Church. He shows that this love is the cause why the Father does all things by his hand. For when he says that the Father SHOWTH to him this word must be understood to denote communication, as if he had said, "As the Father hath given to me his heart, so he hath poured out his power on me, that the Divine glory may shine in my works, and -- what is more -- that men may seek nothing Divine but what they find in me." And, indeed, out of Christ it will be in vain to seek the power of God. He will show him greater works than these. By these words he means that the miracle, which he had performed in curing the man, was not the greatest of the works enjoined on him by the Father; for he had only given in it a slight taste of that grace of which he is properly both minister and Author; namely, to restore life to the world. That you may wonder. By adding these words, he indirectly charges them with ingratitude in despising so illustrious a demonstration of the power of God; as if he had said, "Though you are dull and stupid, yet the works which God shall afterwards perform by me will draw you, however reluctantly, into admiration." Yet this appears not to have been fulfilled, for we know that seeing, they saw not; as Isaiah also says that the reprobate are blind amidst the light of God. I reply, Christ did not now speak of their disposition, but only threw out a suggestion as to the splendor of the demonstration which he would soon afterwards give that he was the Son of God.

The Father loveth the Son - This authority he traces to the love which the Father has for him - that special, ineffable, infinite love which God has for his only-begotten Son, feebly and dimly illustrated by the love which an earthly parent has for an only child.
Showeth him - Makes him acquainted with. Conceals nothing from him. From apostles, prophets, and philosophers no small part of the doings of God are concealed. From the "Son" nothing is. And as God shows him "all" that he does, he must be possessed of omniscience, for to no finite mind could be imparted a knowledge of "all" the works of God.
Will show him - Will appoint and direct him to do greater works than these.
Greater works than these - Than healing the impotent man, and commanding him to carry his bed on the Sabbath day. The greater works to which he refers are those which he proceeds to specify - he will raise the dead and judge the world, etc.
May marvel - May wonder, or be amazed.

Greater works than these - Two of these he immediately mentions: Raising the dead, John 5:21. And judging the world, John 5:22.
That ye may marvel - Or, So as to make you wonder. Our Lord sometimes speaks of himself as God, and sometimes as the ambassador of God. As he had a human and Divine nature, this distinction was essentially necessary. Many errors have originated from want of attention to this circumstance.

For the Father loveth the Son,.... As being his Son, his image, the brightness of his glory, and the express image of his person; as being of the same nature, and having the same perfections, and so equal to him; See Gill on John 3:35;
and showeth him all things that himself doth; not as if he was ignorant of them, since he lies in the bosom of his Father, is the wisdom of God, is the omniscient God, that knows all things; not only all things in men, but all things in God, even the deep things of God: but this is said of the Father, as consulting with him, communicating his designs to him, as his equal; doing nothing without him, as he never did in the works of nature, or of grace: he drew the plan of peace, reconciliation, and salvation in him; he made the worlds by him; and he does nothing in the government of the world without him; and indeed he shows him all things he does, by doing all things; and by him he shows himself, and his works, to men:
and he will show him greater works than these, or he will do greater works by him than these: either than the works of creation; namely, the redemption of the elect, the justification of their persons by his righteousness, and pardon of their sins through his blood, and the regeneration and conversion of them by his Spirit and grace; either of which is a greater work than the making of the world: or greater than he has done under the Old Testament dispensation; than the redeeming of Israel out of Egypt, leading them through the wilderness, and settling them in the land of Canaan; giving them the law, the statutes, and ordinances of God, and working miracles among them: for the redemption of God's people, by Christ, from sin, Satan, the world, the law, death, and hell, the publishing of the Gospel, the effusion of the Spirit, and setting up of the Gospel dispensation, are greater works than these; and more and greater miracles were wrought by Christ than by Moses, or any prophet under the former dispensation. Though rather the sense is, that greater miracles would be shown, and done by Christ, than these he had now done, in curing a man of his disorder, who had had it eight and thirty years, and bidding him take up his bed and walk; such as raising Jairus's daughter to life, when dead, and the widow of Naim's son, when he was carrying to the grave, and Lazarus, when he had been dead four days:
that ye may marvel; this was not properly the end of these greater works shown to, and done by Christ, which were to prove his divine sonship, his proper deity, his true Messiahship, to confirm the faith of his followers in him, and for the glory of God; but this eventually followed upon them: some wondered at them, and believed in him; and others were amazed at them, and confounded by them.

Father loveth . . . and showeth him all, &c.--As love has no concealments, so it results from the perfect fellowship and mutual endearment of the Father and the Son (see on John 1:1; John 1:18), whose interests are one, even as their nature, that the Father communicates to the Son all His counsels, and what has been thus shown to the Son is by Him executed in His mediatorial character. "With the Father, doing is willing; it is only the Son who acts in Time" [ALFORD]. Three things here are clear: (1) The personal distinctions in the Godhead. (2) Unity of action among the Persons results from unity of nature. (3) Their oneness of interest is no unconscious or involuntary thing, but a thing of glorious consciousness, will, and love, of which the Persons themselves are the proper Objects.
show him greater things, &c.--referring to what He goes on to mention (John 5:21-31), comprised in two great words, LIFE and JUDGMENT, which STIER beautifully calls God's Regalia. Yet these, Christ says, the Father and He do in common.

The Father showeth him all things that himself doth - A proof of the most intimate unity. And he will show him - By doing them. At the same time (not at different times) the Father showeth and doth, and the Son seeth and doth. Greater works - Jesus oftener terms them works, than signs or wonders, because they were not wonders in his eyes. Ye will marvel - So they did, when he raised Lazarus.
