John 17:4

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."

This chapter is a prayer, it is the Lord's prayer, the Lord Christ's prayer. There was one Lord's prayer which he taught us to pray, and did not pray himself, for he needed not to pray for the forgiveness of sin; but this was properly and peculiarly his, and suited him only as a Mediator, and is a sample of his intercession, and yet is of use to us both for instruction and encouragement in prayer. Observe, I. The circumstances of the prayer (Joh 17:1). II. The prayer itself. 1. He prays for himself (Joh 17:1-5). 2. He prays for those that are his. And in this see, (1.) The general pleas with which he introduces his petitions for them (Joh 17:6-10). (2.) The particular petitions he puts up for them [1.] That they might be kept (Joh 17:11-16). [2.] That they might be sanctified (Joh 17:17-19). [3.] That they might be united (Joh 17:11 and Joh 17:20-23). [4.] That they might be glorified (Joh 17:24-26).

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.
