“I have glorified You on earth. I have finished the work you have given me to do.” (John 17:4, MEV).
The word signifies his performing every part of his undertaking in the most complete and perfect manner. Herein he glorified his Father; he pleased him, he praised him. It is the glory of God that his work is perfect, and the same is the glory of the Redeemer; what he is the author of he will be the finisher of.
