B: I like that one A: faith is tantamount to an after-image, and not something one has any wilful control over. One doesn't "keep the faith", in truth, or for that matter lose it, but rather simply has the opportunity to observe the phenomenology of its duration, at best to ponder whether the (source of the) image might return... or perhaps whether one can actually see into the darkness. (I tend to think of candles when I think of after-images.)
What seems to complicate this, though, is the idea of having "faith in faith," such that a recursion of belief-feedback loops the after-imaging into a seemingly separate epiphenomenal dimension. It no longer matters whether your friends ever pick you up, but rather just the thought that you once believed they would, which suffices to justify maintaining the faith. Believing one can see in the dark, I suppose.
