Faith, to be faith, must center around something that is not known. Faith, to be faith, must go beyond that for which there is confirming evidence. Faith, to be faith, must go into the unknown. Faith, to be faith, must walk to the edge of the light, and then a few steps into the darkness. If everything has to be known, if everything has to be explained, if everything has to be certified, then there is no need for faith. Indeed, there is no room for it.
