'Vine' in the Bible

"I am the true vine and my Father is the gardener.

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.

"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.
