Assess your belief in prayer through these words from Wayne Grudem:
“If we were really convinced that God actually does respond to our prayers and change the way he acts, and therefore that God actually does bring about remarkable changes in the world in response to prayer, as Scripture repeatedly teaches that he does, then we would pray much more than we do. If we pray little, it is probably because we do not really believe that prayer accomplishes much at all.”
