John 16:24

Hitherto ye have asked nothing in my name.

When he taught his disciples what we are wont to style the Lord's Prayer, he did not direct that the petition should be in his name, for his relation to the Father was not yet unfolded. It was only as the end of his earthly sojourn approached that he directed prayer in his name. When he ascended on high he became our Divine Mediator, "our Advocate with the Father," our "High Priest who maketh intercession for us." His is not only the "only name whereby we must be saved," but through which we have access to the Father. Hence, if our petitions would carry any recommendation they must ascend in the name of the Son. Indeed "whatever we do, all must be done in the name of the Lord Jesus." See also Ephesians 1:21 and Philippians 2:9-10. God has determined that his name shall be exalted above every name.
