Matthew Poole and continuators on John 15:7

7 If ye abide in me, and my words abide in you , ye shall ask what ye will, and it shall be done unto you p:

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 as you by faith embrace the promises, and by obedience live up to the precepts which I have given you: for without these, tho 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 Iohn 5.14. believing, Matth. 21.22. in the Name of Christ, Chap. 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 us.
