John 15:1, 4-5

“I am the true vine, and my Father is the farmer. Remain in me, and I in you. As the branch can’t bear fruit by itself, unless it remains in the vine, so neither can you, unless you remain in me. I am the vine. You are the branches. He who remains in me, and I in him, the same bears much fruit, for apart from me you can do nothing.”
