От Иоанна 5:14

findeth him in the temple--saying, perhaps, "I will go into Thy house with burnt offerings, I will pay my vows which my lips have uttered and my mouth hath spoken when I was in trouble" (Psa 66:13-14). Jesus, there Himself for His own ends, "findeth him there"--not all accidentally, be assured. sin no more, &c.--a glimpse this of the reckless life he had probably led before his thirty-eight years' infirmity had come upon him, and which not improbably had brought on, in the just judgment of God, his chronic complaint. Fearful illustration this of "the severity of God," but glorious manifestation of our Lord's insight into "what was in man."

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).

5:14 stop sinning: Though the man had been healed physically, he still needed to learn obedience to the Lord. The man’s next action (5:15) might indicate that he didn’t listen.
