And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.

People's New Testament

14:13,14 And whatsoever ye shall ask in my name, that will I do. What man would dare to make such a promise? It will be noted, that in order to enjoy the fullness of these glorious promises we must, (1) Believe. They are limited thus in Joh 14:12. Without faith it is impossible to please God. (2) We must ask in his name, or, in dependence upon the merit and intercession of Christ. (3) As shown elsewhere, we must come with a spirit of complete submission to the Father's will, feeling that his will is best, and saying in our hearts, Thy will be done (Mt 6:10 Lu 11:2).

Jamieson-Fausset-Brown Bible Commentary

13, 14. whatsoever ye . ask in my name-as Mediator.

that will I do-as Head and Lord of the kingdom of God. This comprehensive promise is emphatically repeated in Joh 14:14.

Matthew Henry's Concise Commentary

14:12-17 Whatever we ask in Christ's name, that shall be for our good, and suitable to our state, he shall give it to us. To ask in Christ's name, is to plead his merit and intercession, and to depend upon that plea. The gift of the Spirit is a fruit of Christ's mediation, bought by his merit, and received by his intercession. The word used here, signifies an advocate, counsellor, monitor, and comforter. He would abide with the disciples to the end of time; his gifts and graces would encourage their hearts. The expressions used here and elsewhere, plainly denote a person, and the office itself includes all the Divine perfections. The gift of the Holy Ghost is bestowed upon the disciples of Christ, and not on the world. This is the favour God bears to his chosen. As the source of holiness and happiness, the Holy Spirit will abide with every believer for ever.
