When we are defeated and God does not speak, He is leading us to the end of ourselves and to a complete confidence in Him. There is no substitute for that. We try to help God out, and inflate our faith, and make long prayers, but nothing happens. There is prayer which shows no self-confidence, which cries out in the midst of doubt and fear: “I don’t know whether it is any use or not to do so, but I believe!” God can use faith that is exercised in the midst of extreme doubt. Faith as small as a grain of mustard seed.
