I think the debate topic statement and the explanation of it are different, and divided by a fine line.

Faith, I agree, is an important pillar of any relationship; without it, a relationship fails without doubt. However, just because it is present does not make or guarantee the relationship. People carry faith in things that is unwarranted, where the basis, truths, or foundation of faith is undeserved or unsupported.

Ideally one would hope that faith, even based on upon best evidence or supposition, will sustain and carry us through and triumph over all, esp. As regards human relationships. But no matter the faith--if it is blind and not tempered by thought and other senses-- it will not carry us through with a person who is apt to take advantage of our faith and trust. One must look to our god-given ability to watch, listen, keep an open mind, and critically think. It is a fine line to walk and a balance that most of find us hard pressed to keep when we love someone so much, and want so to believe in one another. We are human. We want to be able to trust and have faith. Not everyone will deserve it, unfortunately, and some will prove our faith wrong.

 When my husband and I married each other ten years ago I believed and trusted that we would be together forever. We never had problems trusting each other or problems with commitment. Then one day he gave me divorce papers! Now our marriage is over and I see that what I believed the future would hold, or my faith in the relationship had nothing to do with the actual outcome of events. No belief system, or "faith" is going to alter the future.
