9. The Bible is a progressive revelation. Early Biblical writers did not have as much information as did later Biblical writers. For example, various mysteries were revealed with the first advent of Christ. Old Testament Prophets were not given information concerning the church. Old Testament Prophets did not understand that there were to be two advents of the Messiah. Even though revelation is progressive, the information given in the Old Testament is still valuable.
