Right before going to the cross at Calvary, Jesus gave his disciples some last-minute promises at what we call the Lord's supper. He told them he was about to leave, but he promised them that he would send Holy Spirit to be with them. He would empower, comfort, teach, and guide them through their journey of faith. On the day of Pentecost, that promise was fulfilled, and Holy Spirit came into his present-day ministry. Holy Spirit's ministry is still in effect today. In this book, you will discover the biblical plan, purpose, and power of his ministry. All Christians need to understand his part in their journey of faith. The author presents the biblical facts concerning Holy Spirit's ministry as well as personal insights and illuminations given to him by Holy Spirit. You will experience sweet communion with Holy Spirit as you grow in your biblical knowledge of him and as you seek to know him better.
