Within evangelical theology, dispensational and covenant theology largely frame how people “put together” their Bible and, as such, function as dominant theological viewpoints. Each “system” serves as an interpretive grid for understanding the story line of Scripture and thus functions as “whole-bible theologies” (i.e. biblical theologies) which lead to systematic theological conclusions.
In this way, both views are similar in their attempt to discern the overall unity of God’s revelation, from creation to the new creation.
