John Calvin Commentary John 10:15

"even as the Father knoweth me, and I know the Father; and I lay down my life for the sheep." — John 10:15 (ASV)

As the Father knows me. It is unnecessary, and not even expedient, that we should enter into those thorny questions: How is it that the Father knows his Wisdom? For Christ simply declares that, insofar as he is the bond of our union with God, he is placed between Him and us. It is as if he had said that it is no more possible for him to forget us than for him to be rejected or disregarded by the Father.

At the same time, he demands the duty we mutually owe him. For, as he employs all the power he has received from the Father for our protection, so he wishes that we should be obedient and devoted to him, just as he is wholly devoted to his Father and refers everything to him.
