John 5:23

honour the Son as . . . the Father--As he who believes that Christ in the foregoing verses has given a true account of His relation to the Father must of necessity hold Him entitled to the same honor as the Father, so He here adds that it was the Father's express intention in making over all judgment to the Son, that men should thus honor Him. honoureth not the Father--does not do it in fact, whatever he may imagine, and will be held as not doing it by the Father Himself, who will accept no homage which is not accorded to His own Son.

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).

5:23 the Father . . . sent him: In the ancient world, a person could send an authorized representative to seal a contract or make an authoritative decision. Jesus claimed to be God’s representative, so obeying Jesus is the same as obeying God, and dishonoring him is dishonoring God.
