How do the Old Testament and the New Testament connect?

The OT is the history of who we are, as humans and as Christians. The modern church (Catholic, Protestant, and non-denominational) is not teaching congregants about the vital linkage between the OT and the NT. We live in a time when narrative matters more than facts, and the promotion of emotion overrides the necessity of knowing history and seeing the inescapable connections between what was and what is. If you don’t understand what was, you will never grasp what is.
