The purpose of this book is to introduce a Trinitarian Prayer model. After years of traditional models and principles of prayer, the author continued to struggle in prayer until the renewing of the forgotten Trinity re-emerged that led the author to a Trinitarian prayer showing him how God initiates prayer, Christ mediates prayer, and the Holy Spirit draw us into the perichoretic dance of mutual indwelling.This author will provide biblical and theological constructs to support this prayer model. The project was presented in one church. A pre- and post-questionnaire was given, and a data analysis of the project was provided. The author created a seminar consisting of three sessions to train participants of the local church on Trinitarian prayer with the understanding that the participants have no or little professional training in the significance of the Trinity or Trinitarian prayer.It is not assumed that this project is the only training program for this prayer model, yet it is this author's vision that this prayer model or its concept will be spread to the community of faith, thus widening the boundary of Christian influence and ministry of prayer in the Body of Christ.
