John 17:4

“I have glorified thee on the earth, etc.] 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…”

“I have glorified thee on the earth--rather, "I glorified" (for the thing is conceived as now past). I have finished--I finished. the work which thou gavest me to do--It is very important to preserve in the translation the past tense, used in the original, otherwise it might be thought that the work already "finished" was only what He had done before uttering that prayer; whereas it will be observed that our Lord speaks throughout as already beyond this present scene (Joh 17:12, &c.), and so must be supposed to include in His "finished work" the "decease which He was to accomplish at Jerusalem."”

“Have glorified thee - In my instructions and life. See his discourses everywhere, the whole tendency of which is to put honor on God. I have finished the work - Compare John 19:30. When he says “I have finished,” he probably means to include also his death. All the preparations for that death were made. He had preached to the Jews; he had given them full proof that he was the Messiah; he had collected his disciples; he had taught them the nature of his religion; he had given them his parting counsel, and there was nothing remaining to be done but to return to God. We see here that Jesus was careful that his great and important work should be done before his dying hour. He did not postpone it…”

“I have finished the work - Thus have I glorified thee, laying the foundation of thy kingdom on earth. John 17:5”

“17:4 Jesus’ miracles displayed God’s glory for the world to see (1:14). This task was finished; Jesus’ life and obedience had glorified God.”

“glorified: Joh 12:28, Joh 13:31, Joh 13:32, Joh 14:13 finished: Joh 4:34, Joh 5:36, Joh 9:3, Joh 14:31, Joh 15:10, Joh 19:30; Act 20:24; Ti2 4:7 John 17:5”
