And hath given him power. He again repeats that the Father hath given him dominion, that he may have full power over all things in heaven and in the earth. The word (exousia) here denotes authority Judgment is here put for rule and government, as if he had said, that the Father had appointed him to be King, to govern the world, and exercise the power of the Father himself. Because he is the Son of man. This reason, which is immediately added, deserves particularly to be observed, for it means that he comes forth to men, adorned with such magnificence of power, that he may impart to them what he has received from the Father. Some think that this passage contains nothing else than what is said by Paul, that Christ, having been in the form of God emptied himself by taking upon him the form of a servant, and humbled himself even to the death of the cross; and therefore God hath exalted him, and given him a name more illustrious than any name, that every knee may bow before him (Philippians 2:7-10.) But for my own part, I regard the meaning as more extensive: that Christ, so far as he is man, was appointed by the Father to be the Author of life, that it may not be necessary for us to go far to seek it; for Christ did not receive it for himself, as if he needed it, but in order to enrich us by his wealth. It may be summed up thus: "What had been hidden in God is revealed to us in Christ as man, and life, which was formerly inaccessible, is now placed before our eyes." There are some who separate this argument from its immediate connection, and join it to the following clause; but this is a forced interpretation, and is at variance with Christ's meaning.

Hath given him authority - Hath appointed him to do this. Has made him to be judge of all. This is represented as being the appointment of the Father, Acts 17:31. The word "authority" here (commonly rendered "power") implies all that is necessary to execute judgment - all the physical power to raise the dead, and to investigate the actions and thoughts of the life; and all the "moral right" or authority to sit in judgment on the creatures of God, and to pronounce their doom.
To execute judgment - To do judgment - that is, to judge. He has appointment to "do justice;" to see that the universe suffers no wrong, either by the escape of the guilty or by the punishment of the innocent.
Because be is the Son of man - The phrase "Son of man" here seems to be used in the sense of "because he is a man," or because he has human nature. The term is one which Jesus often gives to himself, to show his union with man and his interest in man. See the notes at Matthew 8:19-20. It is to be remarked here that the word "son" does not have the article before it in the original: Because he is A son of man - that is, because he is a man. It would seem from this that there is a propriety that one in our nature should judge us. What this propriety is we do not certainly know. It may be:
1. Because one who has experienced our infirmities, and who possesses our nature, may be supposed by those "who are judged" to be better qualified than one in a different nature.
2. Because he is to decide between "man" and "God," and it is proper that our feelings, and nature, and views should be represented in the judge, as well as those of God.
3. Because Jesus has all the feelings of compassion we could ask - all the benevolence we could desire in a judge; because he has ShowN his disposition to defend us by giving his life, and it can never be alleged by those who are condemned that their judge was a distant, cold, and unfriendly being.
Some have supposed that the expression "Son of man" here means the same as "Messiah" (see Daniel 7:13-14), and that the meaning is that God hath made him judge because he was the Messiah. Some of the ancient versions and fathers connected this with the following verse, thus: "Marvel not because I am a man, or because this great work is committed to a man apparently in humble life. You shall see greater things than these." Thus, the Syriac version reads it, and Chrysostom, Theophylact, and some others among the fathers.

Because he is the Son of man - Because he is the Messiah; for in this sense the phrase, Son of man, is often to be understood. But some join this to the next verse thus: - Marvel not at this, because he is the Son of man.

And hath given him (i) authority to execute judgment also, because he is (k) the Son of man.
(i) That is, high and sovereign power to rule and govern all things, in so much that he has power over life and death.
(k) That is, he will not only judge the world as he is God, but also as he is man, he received this from his Father, to be judge of the world.

And hath given him authority to execute judgment also,.... Both in his church and kingdom, in the present state of things, and at the last day, when all shall stand before his judgment seat: and that
because he is the son of man; truly and properly man; because though he was in the form of God, and equal to him, yet became man, and was in the form of a servant: and so reads the Ethiopic version, "because the Son of God is the son of man"; and therefore the authority of executing judgment, according to the council and covenant of peace, is committed to him; or that men might have a visible judge, or be judged by one in their own nature: agreeably the Persic version renders it, "because the Son himself is he who judges the sons of men"; or rather because he is that son of man spoken of in prophecy, especially in Daniel 7:13; by whom is meant the Messiah, as the Jews themselves allow (f), and who was not a mere man, but the man God's fellow; and so being omniscient and omnipotent, was equal to such a work, which otherwise he would not have been; See Gill on John 5:22. The Syriac version joins this clause to the beginning of John 5:28, and reads it thus, "because he is the son of man, marvel not at this"; let this be no obstruction to your faith of his quickening the dead, and having authority to execute judgment on all; since, though the son of man, he is not a mere man, but God over all, as what is next ascribed to him manifestly shows.

because he is the Son of man--This seems to confirm the last remark, that what Christ had properly in view was the indwelling of the Son's essential life in humanity as the great theater and medium of divine display, in both the great departments of His work--life-giving and judgment. The appointment of a Judge in our own nature is one of the most beautiful arrangements of divine wisdom in redemption.

Because he is the Son of man - He is appointed to judge mankind because he was made man.
