Faith Works By Doubt
The idea that belief requires a certain degree of disbelief is interesting. For example, if we come to God and believe that He is God and that He rewards our diligence, then we must disbelieve any thought that seeks to contradict this premise. Since faith and doubt are both the product of hearing or seeing, then faith demands that we censor or nullify any internal notion that is contrary. Abraham and Sarah believed God and disbelieved their bodies.
