I have glorified thee on the earth
This is made use of as a reason and argument, why the Father should glorify him: Christ glorified his Father personally, as he held forth and expressed the glory of his person; and verbally, by ascribing, on all occasions, praise and glory to him; and really, or by deeds, and that by various ways: as in and by his ministry; by asserting he had his mission, qualifications, and doctrine, from him as a prophet; his principal work was to declare his Father's mind and will, his love and grace; nor did he seek his own, but his Father's glory: and by his miracles: for though these were proofs of his deity and Messiahship, and displays of his own glory; yet the glory of his Father, especially of his power, was eminently seen in them, for he referred them to him; and these were often the means of men's glorifying the God of Israel: and by his whole life and conversation, which was entirely according to the will of God; and every action of it was directed to his glory; particularly he glorified him by his early regard to his will, and the business he sent him about; by his zeal for his Father's house; and by the exercise of the various graces of faith, hope, and love upon him: and as by his life, so at his death, even all the while he was "on the earth"; where God had been dishonoured by the sin of men; where Christ now was debased in human nature, and even that was for the glory of God; and this is said in distinction from heaven, where God is glorified by the angels, and where Christ would shortly be glorified in his human nature:
I have finished the work which thou gavest me to do;
by "the work" is meant obedience to the will of God; the destruction of all spiritual enemies, as sin, Satan, the world, and death; and the redemption and salvation of his people, which was "given" him to do: he did not take it upon himself, but being called to it he readily accepted of it; it was appointed, and cut out for him, in the council and covenant of grace; he was thoroughly acquainted with it; and though it was difficult, it was pleasant and delightful to him; nor did he leave it till he could say it is "finished"; as it was by himself alone, without the help of man; and is so complete that nothing can be added to it; and so firmly done, that it cannot be unravelled by men and devils: he speaks of it as done, because the time was come to finish it, and he was sure of the accomplishment of it.
