Ligon Duncan, Chancellor & CEO“This book is an aid, exhortation, and encouragement to ministers in their private prayer. And gospel ministers who want to be faithful love to be helped, exhorted, and encouraged in the main things of the Christian life and ministry by other faithful ministers. As Pastor Irving walks us through the subject, addressing the duty, difficulty, discipline, and delight of the minister’s practice of private prayer, he speaks to us as a brother, pastor, and friend.”
