I think he means it more of scale of denial. It isn't so much of blind faith as the fact that it gives ppl something to believe. Something to make everything seem good, no matter how bad things in real life get. No matter what heppens, god has a plan and after we die we WILL be repayed for everything. All we have to do is believe. So yeah, it relaxes you and dulls senses, but I think largely he means it is a artificial escape into a peacefulness that some ppl need to escape reality and the possible futility of life just ceasing upon death w/o any reparations or 2nd chances
