A Handbook on Personal Evangelism Even if communities understand how to follow the principles of spiritual warfare, the actually winning of souls usually occurs on the personal level. Big-picture evangelistic strategy must be complemented by an understanding of personal evangelism. Weapons & Tactics teaches individual Christians how to apply the evangelistic principles described in Principles of War. Using thorough analysis of Scripture and real-life examples, Jim Wilson provides insight on spiritual weapons (what God has given us to fight with) and tactics (the effective use of those weapons) with simple, powerful language. Weapons & Tactics calls us to personal, life-changing obedience as we follow our captain in the fight.
