And all things that are mine are thine. The object of the former clause is to show that the Father will assuredly listen to him. "I do not," says he, "plead with thee for any but those whom thou acknowledgest to be thine, for I have nothing separated from thee, and therefore I shall not meet with a refusal." In the second clause, and thine are mine, he shows that he has good reason for caring about the elect; for they are his in consequence of their being his Father's. All these things are spoken for the confirmation of our faith. We must not seek salvation anywhere else than in Christ. But we shall not be satisfied with having Christ, if we do not know that we possess God in him. We must therefore believe that there is such a unity between the Father and the Son as makes it impossible that they shall have anything separate from each other. And I am glorified in them. This is connected with the second clause of the verse, and thine are mine; for it follows that it is reasonable that he, for his part, should promote their salvation; and this is a most excellent testimony for confirming our faith, that Christ never will cease to care for our salvation, since he is glorified in us.

I am glorified in them - Christ speaks of the things which were not, but which should be, as though they were. He anticipates the glorifying of his name by the successful preaching of the apostles.

And all mine are thine, and thine are mine,.... Christ is speaking not of things but of persons; otherwise all the perfections of his nature as God, and all the works he did, and doctrines he taught as man, were of his Father; as all the perfections of his Father, his nature, his names, his works, his worship, were his; the same that belongs to the one belongs to the other: but persons are here meant, and these the elect of God, particularly the apostles, who were his and his Father's; belonged to them both by election, covenant transactions, redemption, and efficacious grace in conversion; which mutual interest arises from an union in nature, an agreement in covenant, and a conjunction in operation:
and I am glorified in them: or by them, they ascribing all divine perfections, works and worship to him; attributing the whole of their salvation to him, and giving him all the glory of it; believing in him; walking worthy of him, in their lives and conversations; suffering patiently and cheerfully for his sake; and abiding by his Gospel and ordinances; and he will be glorified by them, and in them hereafter, and that to all eternity.

all mine are thine, and thine are mine--literally, "All My things are Thine and Thy things are Mine." (On this use of the neuter gender, see on John 6:37-40). Absolute COMMUNITY OF PROPERTY between the Father and the Son is here expressed as nakedly as words can do it. (See on John 17:5).

I am glorified in them. Christ's glory here upon the earth is manifested by his disciples.

All things that are mine are thine, and that are thine are mine - These are very high and strong expressions, too grand for any mere creature to use; as implying that all things whatsoever, inclusive of the Divine nature, perfections, and operations, are the common property of the Father and the Son. And this is the original ground of that peculiar property, which both the Father and the Son have in the persons who were given to Christ as Mediator; according to what is said in the close of the verse, of his being glorified by them; namely, believing in him, and so acknowledging his glory.
