'In the meantime, as one has learnt to swim only by acting on the assent in the teeth of all instinctive convinction, so we shall proceed to faith only by acting as if we had it. Adapting a passage in the Imitation one can say "What would I do now if I had full assurance that there was only a temporary trough", and having got the answer, go and do it.'
CS Lewis in Walter Hooper (Ed.), Collected Letters Volume II, p.507.
