John 15:4-6

BBE(i) 4 Be in me at all times as I am in you. As the branch is not able to give fruit of itself, if it is not still on the vine, so you are not able to do so if you are not in me. 5 I am the vine, you are the branches: he who is in me at all times as I am in him, gives much fruit, because without me you are able to do nothing. 6 If a man does not keep himself in me, he becomes dead and is cut off like a dry branch; such branches are taken up and put in the fire and burned.
