A persistent tradition claims that upon being mocked by a skeptic with regard to his doctrine of creation, Saint Augustine was cynically asked, “What was God doing before He created the world?” Augustine’s alleged reply was: “Creating hell for curious souls.”
The reply was, of course, tongue-in-cheek. The Bible doesn’t speak of such a special work of divine creation before creation itself. But Augustine’s bon mot had a serious point that warned against idle speculation of God’s activity in eternity.
However, quite apart from speculation, the Bible has much to say about God’s activity “before” the world was made. The Bible speaks often of God’s eternal counsel, of His plan of salvation and the like. It is a matter of theological urgency that Christians not think of God as a ruler who ad libs His dominion of the universe. God does not “make it up as He goes along.” Nor must He be viewed as a bumbling administrator who is so inept in His planning that His blueprint for redemption must be endlessly subject to revision according to the actions of men. The God of Scripture has no “plan b” or “plan c.” His “plan a” is from everlasting to everlasting. It is both perfect and unchangeable as it rests on God’s eternal character, which is among other things, holy, omniscient, and immutable. God’s eternal plan is not revised because of moral imperfections within it that must be purified. His plan was not corrected or amended because He gained new knowledge that He lacked at the beginning. God’s plan never changes because He never changes and because perfection admits to no degrees and cannot be improved upon.
The covenant of redemption is intimately concerned with God’s eternal plan. It is called a “covenant” inasmuch as the plan involves two or more parties. This is not a covenant between God and humans. It is a covenant among the persons of the Godhead, specifically between the Father and the Son. God did not become triune at creation or at the Incarnation. His triunity is as eternal as His being. He is one in essence and three in person from all eternity.
