John 17:19 - Exposition

And for their sakes —on their behalf— I sanctify , consecrate , myself . The Father had consecrated him and sent him into the world, but over and above all this there were special and sacrificial acts of love and devotion which he made on behalf of his own. He went up voluntarily into the wilderness to be tempted for them; he wrought for them while it was yet day. He now was ready to commend himself to the supreme will of the Father, and to offer himself through the Spirit in his perfected humanity without spot of sin to God. ἁγιάζω is equivalent προσφέρω σοὶ θυσίαν , as Chrysostom says , and it is used for שׁידִּקְהִ ( Exodus 13:2 ; Deuteronomy 15:19 ). Christ is the Priest and the victim, and the dedication of himself to this climax of his consecrated life is for the sake of the disciples (so Lange, Meyer, Godet, and Westcott). That they also may be sanctified indeed —truly or veritably.
