John Calvin Commentary John 10:25

"Jesus answered them, I told you, and ye believe not: the works that I do in my Father`s name, these bear witness of me." — John 10:25 (ASV)

I have told you. Our Lord Jesus does not conceal that he is the Christ, yet he does not teach them as if they were willing to learn. Instead, he reproaches them for their obstinate malice because, although they had been taught by the word and works of God, they had not yet made any progress. Accordingly, he imputes their not knowing him to their own fault, as if he said: “My doctrine is easily enough understood, but the blame lies with you, because you maliciously resist God.”

The works which I do. He speaks of his works, to convict them of being doubly obstinate. For, besides the doctrine, they had a striking testimony in his miracles, if they had not been ungrateful to God. He twice repeats the words, You do not believe, to prove that, of their own accord, they were deaf to doctrine and blind to works, which is a proof of extreme and desperate malice. He says that he did the works in the name of his Father; because his design was to testify to the power of God in them, so that it might be openly declared that he came from God.
