It is a connected, historical, systematic, progressive whole. This includes promises and prophecy and historical record. It records the development of salvation in down to earth, understandable, and experienced instruction. The development is in graded, progressive, stages.

The preparation for salvation in the Old Testament is clearly formed and moves unto its goal.
