And all mine are thine, and thine are mine. — Better, And all My things are Thine, and Thy things are Mine. The Authorised version leaves the impression that the pronouns are masculine, and that persons are exclusively meant; whereas the words are all-inclusive, and assert absolute community in all things between the Father and the Son.
And I am glorified in them. — The division of verses is unfortunate, as the last words of this verse are closely connected with the last words of John 17:9, and the general assertion which intervenes is a parenthesis. The thought is, “For they are Thine (and all My things are Thine, and Thy things are Mine), and I am glorified in them.” The fact that Christ is glorified in them forms, then, a second reason for His special prayer for them. The tense is perfect. Its accomplishment is already in part realised (John 17:6-8; comp. John 15:8), and is more fully to be realised in that future of the Spirit’s work which all through this chapter is regarded as present. (Comp. Note on John 16:14.)
