I hoped this book would assist in my Bible studies as an amplifier of feasts as set forth in the Old Testament and as practiced by Jewish people historically. What I encountered instead was an instrument for a faithful Adventist to argue the Ten Commandments and to defend the seventh day Sabbath. Disappointed, I finished it and found another book that I hope will expound more clearly the feast practices for aid in my studies. I prefer books that expound, not preach, and which reference various sources, not promote ideas with only rhetoric.
