The anonymous author of the book of Hebrews says it’s ‘the substance of things hoped for, the evidence of things not seen.’ (11.1)
Hoping for ‘things’ like perfection, resurrection, eternal life, heaven (not to mention the ability to move mountains), the likes of which no-one has ever achieved, is nothing but wishful thinking. Despite what the Hebrews author says, wishful thinking isn’t evidence of anything – except a capacity for wishful thinking.
By it’s very nature, then, faith is not evidence, but the very opposite. It is the effort to believe in things for which there is no evidence and the delusional insistence that the imagined is more real than that which is.
