Through his distinguished career as a pastor, professor, and theologian, Haddon Robinson mentored and raised up many powerful men and women of God. In this moving tribute, R. Larry Moyer, founder and CEO of EvanTell, reflects on the 45 most significant lessons that he learned from his friend and mentor. Over the years, Dr. Robinson provided a depth of insight into Larry’s character and circumstances, and opened many doors for Larry that eventually led to the launch of EvanTell. After 45 years of evangelism ministry with EvanTell, Dr. Moyer reflects on the way that Dr. Robinson’s teaching has echoed down the years and stood the test of time. As a friend and a guide, Dr. Robinson supported and guided Larry in life, leadership, speaking, and evangelism. A Mentor’s Wisdom and the lessons it contains testify to the enduring influence of a pastor and teacher dedicated to training up the church to build the kingdom of God.
