John Calvin Commentary John 12:28

"Father, glorify thy name. There came therefore a voice out of heaven, [saying], I have both glorified it, and will glorify it again." — John 12:28 (ASV)

Father, glorify your name. By these words he testifies that he prefers the glory of the Father to all other things, and even neglects and disregards his own life. And the true regulation of all our desires is to seek the glory of God in such a manner that all other things will give way to it; for it ought to be reckoned by us an abundant recompense, leading us to endure patiently all that is vexatious or irksome.

I have both glorified it. It is as if he had said, 'I will finish what I have begun'; for God never leaves the work of his hands imperfect as it is said in Psalm 138:8. But since it is the purpose of God to prevent the offense of the cross, he not only promises that the death of Christ will be glorious, but also mentions with commendation the numerous ornaments with which he had already adorned it.
