'Bear Fruit' in the Bible

Every branch that does not bear fruit in me, he removes it, and every [branch] that bears fruit, he prunes it in order that it may bear more fruit.

Remain in me, and I in you. Just as the branch is not able to bear fruit from itself unless it remains in the vine, so neither [can] you, unless you remain in me.

You did not choose me, but I chose you and appointed you that you should go and bear fruit, and your fruit should remain, in order that whatever you ask the Father in my name he will give you.
