I suggest you read a wonderful book, which is rather deep on the subject of the Holy Spirit. It gives absolute detail about Rees Howell’s decision to follow Christ. Rees Howell was a minister, and missionary. His book is wonderful. Reese Howell, Intercessor, by Norman Grub. I don’t have the under liner on my computer keyboard. This book is a reasonable price at local Christian bookstores. It can be ordered.
Changes after the filling of the Holy Spirit are that you are in submission to God the Father, Jesus Christ, and to the leading of the Holy Spirit who dwells within you. You will read the first 50 pages of this book and won’t be able to put it down. It is a wonderful explanation of what happened when he surrendered fully to God.
