Bible Verses About Union With Christ: Necessary to fruitfulness

Abide in me, and I in you: as the branche cannot beare fruite of it selfe, except it abide in the vine, no more can ye, except ye abide in me.

I am that vine: ye are the branches: he that abideth in me, and I in him, the same bringeth forth much fruite: for without me can ye doe nothing.
