Expositor's Bible Commentary Commentary John 17:4

"I glorified thee on the earth, having accomplished the work which thou hast given me to do." — John 17:4 (ASV)

Although the final act of his career remains to be performed, Jesus asserts that he has completed his task. He takes for granted that the last step will be taken (cf. 12:27–28). Though aware that he has the option of refusing the Cross and so escaping death, he has resolved irrevocably to complete the work for which he has been sent. To all intents and purposes it is already done. In spite of many obstacles, Jesus never once faltered from doing the Father’s will. He now has one main petition: that the Father will receive him back to the glory he relinquished to accomplish his task . This petition for a return to his pristine glory implies unmistakably his preexistence and equality with the Father, confirming 10:30.
