The document discusses the covenants between God and humanity that are described in the Bible. It explains that a covenant is an agreement between two or more parties, and that the Old and New Testaments describe the Old and New Covenants. The Old Covenant promised physical blessings for obedience but was broken by humanity. The New Covenant, established by Jesus, promises eternal life and forgiveness of sins through faith. It is spiritually based rather than dependent on works, and involves God writing his laws on people's hearts rather than on tablets of stone.
