John 5:21

raiseth the dead and quickeneth them--one act in two stages. This is His absolute prerogative as God. so the Son quickeneth them--that is, raiseth up and quickeneth. whom he will--not only doing the same divine act, but doing it as the result of His own will, even as the Father does it. This statement is of immense importance in relation to the miracles of Christ, distinguishing them from similar miracles of prophets and apostles, who as human instruments were employed to perform super-natural actions, while Christ did all as the Father's commissioned Servant indeed, but in the exercise of His own absolute right of action.

We have in the gospels a faithful record of all that Jesus began both to do and to teach, Act 1:1. These two are interwoven, because what he taught explained what he did, and what he did confirmed what he taught. Accordingly, we have in this chapter a miracle and a sermon. I. The miracle was the cure of an impotent man that had been diseased thirty-eight years, with the circumstances of that cure (v. 1-16). II. The sermon was Christ's vindication of himself before the sanhedrim, when he was prosecuted as a criminal for healing the man on the sabbath day, in which, 1. He asserts his authority as Messiah, and Mediator between God and man (Joh 5:17-29). 2. He proves it by the testimony of his Father, of John Baptist, of his miracles, and of the scriptures of the Old Testament, and condemns the Jews for their unbelief (v. 30-47).

5:21 Most Jews firmly believed in resurrection but viewed it as something God alone could accomplish. Jesus claimed that he gives life.
