Matthew Henry Commentary John 14:12-17

"Verily, verily, I say unto you, he that believeth on me, the works that I do shall he do also; and greater [works] than these shall he do; because I go unto the Father. And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. If ye shall ask anything in my name, that will I do. If ye love me, ye will keep my commandments. And I will pray the Father, and he shall give you another Comforter, that he may be with you for ever, [even] the Spirit of truth: whom the world cannot receive; for it beholdeth him not, neither knoweth him: ye know him; for he abideth with you, and shall be in you." — John 14:12-17 (ASV)

Whatever we ask in Christ's name, he will give it to us, and it will be for our good and suitable for our state. 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, counselor, monitor, and comforter. He will abide with the disciples to the end of time; his gifts and graces will 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 favor God shows to his chosen. As the source of holiness and happiness, the Holy Spirit will abide with every believer forever.
