Leviak B. Kelly said this quote

This is why questions must be asked and answered truthfully and why we must train our emotions to coincide with what is actually true. Doubt is a necessary part of faith, otherwise it is a blind faith and a deaf faith that deserves to be a mute faith. For, when Helen Keller, who was deaf, blind and had to learn to speak can come closer to the truth than persons with full sensory capacity, perhaps there is something wrong with our religious and spiritual traditions.
