If I do not the works Lest the Jews might reply that it was in vain for him to boast of sanctification, and of all that depended on it, he again draws their attention to his miracles, in which there was a sufficiently evident proof of his Divinity. This is in the shape of a concession, as if he had said, "I do not wish you to be bound to give me credit on any other condition than that you see the fact plainly before your eyes. [1] You may safely reject me, if God has not openly given testimony to me." The works of my Father. He gives them this name, because those works were truly Divine, and because so great power shone in them, that they could not be ascribed to a man.

1 - "Sinon que vous voyez le faict evident devant vos yeux."

The works of my Father - The very works that my Father does. See John 5:17; "My Father worketh hitherto, and I work." See the note on that place. The works of his Father are those which God only can do. As Jesus did them, it shows that the name "Son of God," implying equality with God, was properly applied to him. This shows conclusively that he meant to be understood as claiming to be equal with God. So the Jews naturally understood him John 10:39, and they were left with this impression on their minds.

If I do not the works, etc. - I desire you to believe only on the evidence of my works: if I do not do such works as God only can perform, then believe me not.

If I do not the works of my Father,.... Not only what the Father had given him to finish, and which he wrought by him as man, but such as were as great as the Father had done, and were equal to them; and which could not be done by any, but by the Father, or by one that is equal with him:
believe me not: Christ appeals to his miracles as proofs of his deity, sonship, and Messiahship, and desires no other credit than what they demand; see Matthew 11:3.

though ye believe not me, believe the works--There was in Christ's words, independently of any miracles, a self-evidencing truth, majesty and grace, which those who had any spiritual susceptibility were unable to resist (John 7:46; John 8:30). But, for those who wanted this, "the works" were a mighty help. When these failed, the case was desperate indeed.
that ye may know and believe that the Father is in me, and I in him--thus reiterating His claim to essential oneness with the Father, which He had only seemed to soften down, that He might calm their rage and get their ear again for a moment.
