The key to life and ministry is just as the Apostle Paul instructed: guard your life and your doctrine. For the student preparing for ministry, there is no better instruction than to build your doctrine through careful attention to God's Word and to build your devotion through continued spiritual disciplines and daily walking in the Spirit. This practical book prepares the student for pastoral or ministerial work, with honest explanation of the spiritual opposition they will face and the necessary wisdom and preparation for fruitful life-long ministry. In Letters to My Students: On Life and Doctrine , Jason K. Allen grounds the wisdom of living for an eternal reward in biblical inerrancy, the sufficiency of Scripture, the exclusivity of Christ, and the doctrine of man. These foundational truths then inform how the pastor or minister should practice the spiritual disciplines, shepherd their family, cherish their church, lead themselves, and preach. A righteous and flourishing life and ministry is the overflow of a heart grounded in God's Word and God's ways.
