This is a wonderful book. I share it in my Clinic. I also use it to test myself on my own Bible knowledge. I test myself after reading a Book of the Bible to see how much information I have retained. My husband and I make a game of it and test each other's knowledge. 4000 questions is a lot of information to have fun with. I also share it with my friends and Bible Study partners. you will really enjoy it if you use it.
