Dispensationalism is the main reason God’s people have had such difficulty in seeing the Scriptures as one unified whole. (The concept of “OT” and “NT” as separate and distinct from each other, has created an unnecessary misunderstanding.) To make the New Testament “Church” something unique/new/different (since the “Church” isn’t in the OT), a system had to be developed to make that preference “fit” into the Scriptures.
