John 15:7 - Matthew Poole's English Annotations on the Holy Bible

Here our Lord expounds what he meaneth by that abiding in him which he before mentioned by another phrase, and my words abide in you, my precepts and promises; so its you by faith embrace the promises, and by obedience live up to the precepts which I have given you: for without these, though the words of Christ may come unto men in the preaching of the gospel, their ears may receive the sound of them, yet the word doth not dwell and abide in the soul: but if the word abides in the souls of men and women, then they may in prayer ask of God what they will, keeping to the conditions and limitations elsewhere required in holy writ, according to God's will, 1 John 5:14, believing, Matthew 21:22, in the name of Christ, 1 Thessalonians 14:13,14, for the honour and glory of God, (to which end all our actions must be directed), and they shall be granted to them.
