16 And I will make prayer to the Father and he will give you another Helper to be with you for ever, 17 Even the Spirit of true knowledge. That Spirit the world is not able to take to its heart because it sees him not and has no knowledge of him: but you have knowledge of him, because he is ever with you and will be in you.
Matthew Henry's Commentary on John 14:16-17
Commentary on John 14:12-17
(Read John 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.
