"And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son." (John 14:13)
In the gospel of John there are at least six promises that, if we pray in Jesus' name, God in Christ will answer our prayer. The first is in our text, which promises that God the Father may be glorified in God the Son. Note also the equivalent promises in John 14:14; 15:16; 16:23-24, 26.
Such promises seem almost too comprehensive and unconditional to be understood literally. The key, however, is the significance of the phrase "in my name." This obviously means more than simply beginning or ending our prayer with this or some similar phrase.
In the first place, we must recognize that it is only through Jesus Christ our mediator that we dare enter the presence of the omnipotent God at all. "No man cometh unto the Father, but by me" (John 14:6), He said. That being true, it also implies that our prayer must be in agreement with what Christ Himself would pray. No Christian should ask for something he knows to be against God's will. "If we ask any thing according to his will . . . we know that we have the petitions that we desired of him" (1 John 5:14-15).
When we come to the Father in Christ's name, we are in a very real sense representing Him. Therefore, we must come with clean hands and motives worthy of the One in whose name we profess to come. Unconfessed, unrepented sin would surely misrepresent Him, and we could hardly speak in His name in such a case. Finally, acknowledging His power and promise, we must come believing, not doubting His Word, if we come in His name.
Then, not only is the Father glorified, as says our text, but we shall rejoice. "Whatsoever ye shall ask the Father in my name, he will give it you. . . . ask, and ye shall receive, that your joy may be full" (John 16:23-24). HMM
