There are 21 vital topics in the bible. We have assembled manuscripts of each topic that are in most cases lists of scriptures associated with the subject and listed by which inspired author wrote on the subject. For example 'the gospel.' The gospel was presented back in the days of Moses. God, John the Baptist, Jesus, John, Peter, Paul and others all taught on the subject of the gospel. What did they teach and who said what? It is absolutely fascinating to read assembled lists on a specific topic by different inspired teachers in the bible. I thought I had a near complete biblical understanding on all of the vital bible topics. But revisiting the bible scriptures in this 'stick to the subject' and 'who said what' format heightened my understanding on every subject...I was often surprised by what I didn't know on a given topic.
