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.

And I will pray the Father, &c.—This connection seems designed to teach that the proper temple for the indwelling Spirit of Jesus is a heart filled with that love to Him which lives actively for Him, and so this was the fitting preparation for the promised gift.
he shall give you another Comforter—a word used only by John; in his Gospel with reference to the Holy Spirit, in his First Epistle (1Jo 2:1), with reference to Christ Himself. Its proper sense is an "advocate," "patron," "helper." In this sense it is plainly meant of Christ (1Jo 2:1), and in this sense it comprehends all the comfort as well as aid of the Spirit's work. The Spirit is here promised as One who would supply Christ's own place in His absence.
that he may abide with you for ever—never go away, as Jesus was going to do in the body.
