John 15:2

15:2 He takes away every branch that does not bear fruit in me. He prunes every branch that bears fruit so that it will bear more fruit.

John 15:4-6

15:4 Remain in me, and I will remain in you. Just as the branch cannot bear fruit by itself, unless it remains in the vine, so neither can you unless you remain in me.

15:5 “I am the vine; you are the branches. The one who remains in me – and I in him – bears much fruit, because apart from me you can accomplish nothing. 15:6 If anyone does not remain in me, he is thrown out like a branch, and dries up; and such branches are gathered up and thrown into the fire, and are burned up.
