What is prayer? Are we really praying when we pray? Do we know the power of prayer? These matters and others must be understood if we would have a real prayer life and be effective in prayer. In this little volume of collected messages given over a long period of ministry by the author, and which are now translated and published in English for the first time, Watchman Nee shares with us the lessons on prayer that he has learned through the years. He considers prayer to be a mystery, though not something that is incomprehensible. He views prayer as the greatest work to which men are called. It is a working together with God. Through it, God's purpose is accomplished and Satan's intentions are broken. And its benefit to the one who prays is something great as well. Let us therefore follow the admonition of our blessed Lord, who said: Rise and pray" (Luke 22.46).
