John 15:4–6

4 Abide in me, and I in you. As the branch cannot bear fruit by itself, unless it abides in the vine, neither can you, unless you abide in me. 5 I am the vine, you are the branches. He who abides in me, and I in him, he it is that bears much fruit, for apart from me you can do nothing. 6 If a man does not abide in me, he is cast forth as a branch and withers; and the branches are gathered, thrown into the fire and burned.
