John 15:6

⁴ Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.

⁵ I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.

If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.

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.

⁸ Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.

Do read the surrounding verses too, because the context often says more than a single verse.
