To gamble or wager, is to stake something of value on an event with an uncertain outcome.
Hmmm...
Faith is confidence or trust in a person or thing, or a belief that is not based on proof. In religion, faith is a belief in a transcendent reality, a religious teacher, a set of teachings or a Supreme Being.[citation needed] Generally speaking, it is offered as a means by which the truth of the proposition, "things will turn out well in the end," can be enjoyed in the present and secured in the future. This faith appeals to transcendent reality, or that reality which is beyond the range of normal physical experience (e.g. the future).
Looking at these two defintions I think it is fair to say that Faith and Gambling are siblings. Both have an element of chance, both require an upfront stake, decisions made are ultimately based on gut feelings.
Faith is just another word for gambling.
"I have faith that the Church is true"
"I am gambling that the Church is true"
I think I have just gained a better understanding of faith.
