Guarantees

Guarantees are hard to come by.  And the "guarantees" that you may encounter can be loaded with disclaimers and provisions that make them almost meaningless.

But here is a guarantee that is iron-clad:

http://bible.us/John15.5.NIV
"I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing."

Would you like a guarantee that you will bear, not just fruit, but much fruit?  Remain in him.

Would you like a guarantee that you will do nothing fruitful? Separate yourself from him.
