Evangelism: Fulfilling the Promise & the Call to Service is a thoughtful and ministry-centered exploration of the theology, history, and practice of Christian evangelism. Drawing from Scripture, church history, pastoral reflection, and global ministry experience, Dr. John Wesley Foryoh equips readers to understand evangelism not simply as a church activity, but as a Spirit-led calling rooted in the heart of God and the mission of Christ. Covering biblical foundations, practical methods, cultural challenges, leadership development, and contemporary applications, this book is designed to help believers, pastors, church leaders, and ministry workers become more faithful, compassionate, and effective witnesses in today's world.
