At each step in the developing revelation, God promises, “I shall be your God, and you shall be my people.” This theme resounds over and over until it reaches its climax in the person of Jesus Christ--”God with us” (Matt. 1:23).
The contintinunity of God’s redemptive plan, from one administration of the covenant of grace to the next, is the predominant theme of the whole Bible. This is covenant theology. Any failure to grasp and appreciate the essential unity of God’s purpose leads to confusion and misunderstanding. God’s redemptive plan is both comprehensive--embracing every area of life--and unified in purpose.
