John 5:30

I can do nothing of myself, &c. See ver. 19. St. Chrysostom also take notice, that it may be no less with truth said of the Father, that he can do nothing of himself, nor without his Son, nor both of them without the Holy Ghost; because both they, and their actions, are inseparable. (Witham)

[4.] Here is the righteousness of his proceedings pursuant to this commission, v. 30. All judgment being committed to him, we cannot but ask how he manages it. And here he answers, My judgment is just. All Christ's acts of government, both legislative and judicial, are exactly agreeable to the rules of equity; see Prov 8 8. There can lie no exceptions against any of the determinations of the Redeemer; and therefore, as there shall be no repeal of any of his statutes, so there shall be no appeal from any of his sentences. His judgments are certainly just, for they are directed,

Verses 30-38 Our Lord returns to his declaration of the entire agreement between the Father and the Son, and declared himself the Son of God. He had higher testimony than that of John; his works bore witness to all he had said. But the Divine word had no abiding-place in their hearts, as they refused to believe in Him whom the Father had sent, according to his ancient promises. The voice of God, accompanied by the power of the Holy Ghost, thus made effectual to the conversion of sinners, still proclaims that this is the beloved Son, in whom the Father is well pleased. But when the hearts of men are full of pride, ambition, and the love of the world, there is no room for the word of God to abide in them.

(1.) Observe what is here said concerning the Mediator's power to raise the dead and give life. See [1.] His authority to do it (v. 21): As the Father raiseth up the dead, so the Son quickeneth whom he will. First, It is God's prerogative to raise the dead, and give life, even his who first breathed into man the breath of life, and so made him a living soul; see Deut 32 30; 1 Sam 2 6; Ps 68 20; Rom 4 17. This God had done by the prophets Elijah and Elisha, and it was a confirmation of their mission. A resurrection from the dead never lay in the common road of nature, nor ever fell within the thought of those that studied only the compass of nature's power, one of whose received axioms was point blank against it: A privatione ad habitum non datur regressus—Existence, when once extinguished, cannot be rekindled. It was therefore ridiculed at Athens as an absurd thing, Acts 17 32. It is purely the work of a divine power, and the knowledge of it purely by divine revelation. This the Jews would own. Secondly, The Mediator is invested with this prerogative: He quickens whom he will; raises to life whom he pleases, and when he pleases. He does not enliven things by natural necessity, as the sun does, whose beams revive of course; but he acts as a free agent, has the dispensing of his power in his own hand, and is never either constrained, or restrained, in the use of it. As he has the power, so he has the wisdom and sovereignty, of a God; has the key of the grave and of death (Rev 1 18), not as a servant, to open and shut as he is bidden, for he has it as the key of David, which he is master of, Rev 3 7. An absolute prince is described by this (Dan 5 19): Whom he would he slew or kept alive; it is true of Christ without hyperbole.
