God’s covenant commitment to His people, made in successive promise-bonds, forms the scaffolding within which He builds His church; its shape and growth are determined by it. But like a medieval cathedral, the church is built over centuries; and like a great book, its story is divided into chapters. The word covenant (Hebrew berith, Greek diathēkē) first occurs in the context of the judgment-flood from which only Noah and his family were saved: “I will establish my covenant with you,” God promised (Gen. 6:18). While God brought judgment-curse on the earth (vv. 11–13), by contrast He promised to bless Noah and his seed (9:1).
