'Abides in Me' in the Bible

He who eats My flesh and drinks My blood abides in Me, and I in him.

Believest thou not that I am in the Father, and that the Father is in me? The words which I speak to you I do not speak from myself; but the Father who abides in me, he does the works.

I am the vine, ye are the branches. He that abides in me and I in him, he bears much fruit; for without me ye can do nothing.

Unless a person abides in me, he is thrown away like a pruned branch and dries up. People gather such branches, throw them into a fire, and they are burned up.
