To understand the Bible, it is essential to grasp the sweep of that history from creation to consummation. The one constant theme unfolding throughout the whole Bible is this: God for His own glory has chosen to create and gather to Himself a group of people to be the subjects of His eternal kingdom, to praise, honor, and serve Him forever and through whom He will display His wisdom, power, mercy, grace, and glory. To gather His chosen ones, God must redeem them from sin. The Bible reveals God's plan for this redemption from its inception in eternity past to its completion in eternity future. Covenants, promises, and epochs are all secondary to the one continuous plan of redemption.
