John 10:25

told you, and ye believed not.

He had told them repeatedly (5:19; 8:36, 56, 58), not as plainly, it is true, as he told the Samaritan woman (4:26) and the man blind from birth (9:37), but more plainly than he ever told his disciples before the confession of Peter (Matthew 16:16). He knew what was in their hearts and he simply pointed them to his works, as he had done John the Baptist when his messengers came asking, "Art thou he that should come?" (Matthew 11:2-6.) Indeed the profoundest evidence of his divinity is not his word, but his superhuman life, teachings and works, especially the work that he has continued to do in the world. Even if he had said he was the Christ they would not have understood him, as their idea of the Christ differed as far as the poles from the real Christ.
