Jesus is teaching us here that self-sacrifice, self-surrender, wholehearted service, and total obedience to the Lord is not a burden but rather a joyful expression of submission. Jesus endured the Cross in anticipation of the joy of becoming our Lord & Savior…His total obedience was His joy…the joy of doing that which His Father had sent Him to earth to do…and fulfilling it to the last letter. (Hebrews 12:2) So in this Scripture we see Jesus praying that our joy might continue to fulfill itself until it becomes the same joy as His. And how does this happen? It happens within a right relationship with God, for this is where we will find our personal joy. And as we find our joy & delight in Him, we are blessed…and able to be a blessing to others.
