Another awesome amazing wonderful Christian book
Format: Kindle
This is a very strong wonderful book. I am able to learn more about how to build and strengthen my relationship with God and Jesus. I also learned that Jesus has 50 Commandments and I was able to look this up. I am planning to write them down and follow The 50 Commandments of Jesus. I also learned more about the Witness, The Church Communities, The 144,000 Faithful, and how satan will try to destroy God children(us) and God planes. But we all know God win's. Matthew Robert Payne starts by telling us he is trying to give us a visual of how the end times may go. Everything Matthew Robert Payne talks about is in the bible and Matthew is giving us an example of how the end times could look like. I truly recommended this book. I recommend Matthew Robert Payne books because his books truly help you build your relationship with God Jesus, the Holy Spirit, the ArchAngel's, the Angel's, and the Saint's. I was not a person who likes to read Christian books. But when I became ready to build a relationship with God Jesus, the Holy Spirit, the ArchAngel's, the Angel's, and the Saint's plus I was lead by the Holy Spirit to wonderful authors like Matthew Robert Payne. I became a devoted follower of God Jesus and a person who loves to read Christian books in fact I read nothing but Christian books and enjoying my journey towards God and Jesus. I truly believe Matthew Robert Payne is a wonderful loving caring gentleman who only wants to help his brother's and sister's in Christ to be fulfilled in Christ, and walk like Jesus. So my recommendation is read this book and other wonderful loving caring Matthew Robert Payne books. I'm living proof that Matter Robert Payne books will change your life in a beautiful loving caring way and you will find yourself feeling God Jesus, the Holy Spirit, the Saint's, the ArchAngel's and the Angel's present's in your life. I'm a blessed Christian, wife, mother, family member, Child of God, and sister in Christ. God truly has his hands in Matthew Robert Payne life because he is a awesome amazing wonderful and truthful Christian Gentleman. God Bless

Exciting and insightful revelation presented in an easy-to-read way.
Format: Kindle
Matthew Robert Payne shares his personal revelations, visions, and thoughts on the end times church, the two witnesses, the 144,000 and more with a spirit of integrity and humility. I really enjoyed reading about what God had revealed to him about the two witnesses, it was radical stuff, that was not even slightly on my radar, on in my personal understanding and was exciting and interesting to read. If you want to be a part of the end times church, this part of the book is essential reading. You'll gain insight into what will happen, what you need to do to be safe and how to be used as one of God's end-time harvesters. Learn about Matthew's interpretation of who is the 144,000.This book is a must-read. It will inspire you to start living set apart for Jesus right now where you are. Read the book now!

An optimistic view of the endtimes
Format: Kindle
I like Matthew's writing style.For a subject as esoteric like Revelation, he makes it an easy read. I would have given it 5 stars if this was an audio but for some repetitious statements. He brings to light the pivotal role of the two witnesses and the 144,000 in end-time harvest. It gives you an optimistic view of the future in keeping with the theme of the New Testament. A real blessing to the Bride waiting for the Groom. Maranatha!

End times made (more) simple.
Format: Kindle
Matthew has taken a difficult topic and expanded on it based not only on the Word, but also based on visions, prophecy from others, and revelation knowledge from the Holy Spirit. He gives new ideas and strengthens old ones. For instance, I have always thought the two witnesses in Revelation are Enoch and Elijah because God took them (they did not die) and because man is appointed once to die. This was reinforced by this book, and I believe that it is a leading by the Holy Spirit within the critical framework of the Word. Its a short read and worth your time.
