This volume titled: The Spirit-Filled Life is the first of a three-volume series that completes the basic studies for level C of the ABCDE Discipleship Plan of the Church of the Nazarene in the Mesoamerica Region. The series is called: Filled with the Spirit and covers 9 months of studies. Each book contains 13 discipleship lessons focused on the consolidation and growth needs of people who have recently been incorporated into local church membership. These lessons have been written with the thoughtful discipler/teacher in mind, and offers guidelines about how the teacher should instruct the group of new members in such a way that the class is interesting, dynamic and applicable to their lives. These books present the doctrine and practice of the life of holiness in simple practical language, and at the same time connect with the ideas of the contemporary world. The holy life is studied emphasizing: A) The natural and progressive changes that are produced in the Christian, as a result of the action of the Holy Spirit in one's life; changes that are observable not only by oneself, but by all those around him or her. B) The life full of the love of God as an indispensable requirement to serve the Lord and our fellow man. C) The progressive and total transformation of the life of believers as we become more and more like Jesus Christ. Each lesson presents a new opportunity for God to continue to work and transform each disciple so that we all might become more like Jesus in the way we think, in our emotions, and lifestyle, through bible studies, examples and illustrations, self-assessment exercises, reflection, as well as the opportunity to set new goals for spiritual growth.
