The Secret Life of the Pastor
"In following the examples of Christ and of Paul, we quickly see how the benefits far outweigh the investment of time spent in prayer. A pastor’s prayer life is a strong indication of the closeness of his or her walk with the Lord. Peter urges us to keep prayer a number one priority; “The end of all things is at hand; therefore be serious and watchful in your prayers” (1 Pet. 4:7, NKJV). In these modern times, where the latest and greatest methods fall short, true effectiveness in ministry comes through prayer."
