"The message of faith has helped me in my walk with God in ministry, in family, in health, and in finances, and I trust that this balanced teaching will help you. If you have heard negative talk about the faith movement, you will need to lay aside your presuppositions and allow this series of teachings to bring revelation to your spirit. Without faith it is impossible to please God. You need faith!
Jesus never rebuked anyone for great faith, but He did rebuke those with little faith and no faith. He taught us to have faith in God, yet it is amazing that we who are called “believers” are so often “unbelieving.” This manual will confront unbelief, doubt, and fear. It is my prayer that by the end of these lessons, your faith in God will be activated for miracles."
