Luke 24:49 and Acts 1:8 are parts of the last precious words of our Savior before ascending to heaven. These two commands of the Great Commission have been neglected by a large portion of the church. I believe this book will help you to: 1.Have a better understanding of these two precious commands 2.Fuel discussions across the church 3.Encourage you to desire the dunamis of the Spirit 4.Encourage you and the church to seek the dunamis by persevering in prayer 5.Spark little fires of revival throughout the church 6.Ignite all the small fires into one big fire of revival. I pray to God that as you read this book, it will inspire you to rise up to be among God's Giants in the days to come. The author is a teacher/evangelist. He has shared the gospel tirelessly for over twenty-five years. For over ten years, he preached at Speakers' Corner in London. He has a heart for souls and is expecting God to send revival, especially in London.
