Pastor and civil war chaplain E. M. Bounds penned his slim classic on prayer for the simple reason that Christians don't pray enough. "The little estimate we put on prayer is evident from the little time we give to it," he wrote. "Talking to men for God is a great thing, but talking to God for men is greater still."

Bounds' simple, concise volume can help all Christians rediscover the source of spiritual power in their life.
