In The Fatherhood Principle: God's Design and Destiny for Every Man, Dr. Myles Munroe explores the inherent purpose of all men as fathers, regardless of marital status or biological parenthood. He emphasizes that fatherhood reflects the creative and nurturing nature of God, and is a calling for every man to fulfill in the lives of those around him. Munroe provides practical guidelines for men to become sources, nourishers, sustainers, protectors, teachers, disciplinarians, leaders, heads, caring ones, and developers within their personal spheres of influence. By understanding and embracing these roles, men can fulfill their God-given fatherhood role and step into their true purpose in life.
