Dispensationalism - Progressive revelation

One of the most important underlying theological concepts for dispensationalism is progressive revelation. While some non-dispensationalists start with progressive revelation in the New Testament and refer this revelation back into the Old Testament, dispensationalists begin with progressive revelation in the Old Testament and read forward in a historical sense. Therefore there is an emphasis on a gradually developed unity as seen in the entirety of Scripture. Biblical covenants are intricately tied to the dispensations. When these Biblical covenants are compared and contrasted, the result is a historical ordering of different dispensations. Also with regard to the different Biblical covenant promises, dispensationalism emphasizes to whom these promises were written, the original recipients. This has led to certain fundamental dispensational beliefs, such as a distinction between Israel and the Church.
