Johannes 5:32

There is another--that is, the Father, as is plain from the connection. How brightly the distinction of the Persons shines out here! and I know that the witness, &c.--"This is the Son's testimony to the Father's truth (see Joh 7:28; Joh 8:26, Joh 8:55). It testifies to the full consciousness on the part of the Son, even in the days of His humiliation, of the righteousness of the Father" [ALFORD]. And thus He cheered His spirit under the cloud of human opposition which was already gathering over His head.

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).

5:32 The first witness for Jesus’ defense was God himself. Jesus might have had in mind God’s voice at his baptism (Mark 1:11) or the presence of God that enabled Jesus to perform miracles.
