If ye abide in me, and my words abide in you... — He is now passing from the figure, which recurs again only in John 15:8; John 15:16. We should have expected here, “and I abide in you” (John 15:4); but His abiding in them necessarily accompanies their abiding in Him. The abiding of His words in them is the means by which, and the proof that they do abide in Him. (Comp. John 14:15; John 14:23-24.)
Ye shall ask what ye will, and it shall be done unto you. — The reading is not certain, but the first verb should probably be imperative, “Ask what ye will...” The promise in all its width is the same as that in John 14:13-14 (see Note there), and it is attended by the same condition, for they who abide in Christ, and in whom Christ’s words abide, cannot pray otherwise than in His name.
