I am the vine, you are the branches. Whoever remains in me and I in him will bear much fruit, because without me you can do nothing. (Jn 15:1-8)

Another striking image from the Fourth Gospel, the vine and the branches. And as the Lord reminds us: Remain in me, as I remain in you, for without me you can do nothing.
