Cut it Off and It Will Die

John 15:5 

I am the vine, ye are the branches: 

He that abideth in me, and I in him, 

the same bringeth forth much fruit: 

for without me ye can do nothing.

More beautiful garden analogies ...

If I lop off any of the vines on my pea plants,

I won't get any produce from those vines.

Without Christ - this vine (me) is NOTHING!
