When men or nations enter into agreements, they use a number of methods to finalize those arrangements. Some methods are formal and legal; other methods are informal and personal.
Among those used to "seal a deal" are treaties, accords, contracts, compacts, promises, pledges, and covenants. When the eternal God chose to enter into a special relationship with man, He chose to use the method of the covenant. Specifically, God entered six major covenants. In so doing, He chose to enter them with the nation of Israel. Each of these covenants was directly made through one of history's most important personages. It is crucial that Christians understand these covenants!
