Even the most sincere, the most deeply founded in faith, go through hours of despair. At such times it is important to continue praying. Perhaps it will sound as if we are talking into an echo chamber. Or perhaps we will feel that our efforts are so insignificant, so weak, that our voice can never reach heaven. But prayer never depends on our feeling close to God; he is always close to us, and he does hear us.
