Discipleship Manual: A Guide for Evangelism and/or Discipleship, Designed to Lead Souls into a True Relationship with God In a world where the Christian faith is constantly challenged by shifting ideologies and empty spiritualities, this manual emerges as an urgent and hope-filled response. Conceived as a clear, biblical, and transformative tool, its purpose is to guide believers—whether new or growing in maturity—into a deep and authentic relationship with God. Here, discipleship is not presented as mere theoretical teaching, but as a comprehensive process of character formation in the likeness of Christ, with practical application for daily life. The authors, Dr. Mayelyn Mateo de Arias and Dr. Amaury Arias Rodríguez, write this material with deep conviction and spiritual burden. As pastors, mentors, and servants in the Kingdom, they feel the weight and urgency of making disciples committed to the truth of the Word—disciples who live a genuine, active, and fruitful faith. Every page has been crafted with prayer, love, and passion for souls, with the hope that readers will not only learn but also experience true transformation that leads them to love God with all their being and serve Him faithfully. This manual provides a journey through the essential foundations of the Christian faith: the authority of Scripture, the eternal purpose of humanity, redemption in Christ, the new birth, life in the Spirit, obedience through baptism and the Lord’s Supper, and the call to a consecrated life that bears fruit for the glory of God. It is an ideal guide for both evangelistic efforts and individual or group discipleship, useful for believers, leaders, teachers, and pastors who long to see lives transformed by the power of the Gospel. More than just a book, this manual is an invitation to know Christ, live in Him, and walk in the fullness of His eternal purpose.
