It took me thirty years of studying before I did it, but I did write this book from the voice of God, my Lord and Savior. When God speaks, I run to greet Him. I wrote about 150 Bible studies in the last thirty years all with one finger and was about going to work for our in just teaching. So I always ask God what He wants me to do next. No answer. It took two weeks. I was sitting in my Bible room, and I prayed for God to tell me what next. And this soft voice said, "I want you to write a book on the key of David." So I followed what our Father asked! This book has the strait and narrow way. If this book doesn't get you on your knees and pray to our Lord Jesus Christ for forgiveness of your poor, sick flesh, you cannot stop sinning without the Lord Jesus Christ. Read the book and learn the key of David. You can't go wrong. Do you know why? Read Revelation 3:7 and be blessed.
