How are all the other covenants related to the Abrahamic covenant?

Les explains that the Abrahamic covenant was basically three promises, and within those three promises all the other covenants are involved. The first promise was that out of Abraham would come a nation of people, Israel. The second was that once they became a nation, God would put them in their own geographical area, the promised land, today again the nation of Israel. The third was that a people in a geographical area must have a government, so God Himself would come and be their King, Messiah, Redeemer, and Savior, which includes salvation. Thus all the other covenants are wrapped up inside this one. He adds that you cannot have a viable kingdom without a king, and a king is of no earthly use without a kingdom; the two must come together. When Jesus came and John the Baptist presented Him as Israel's King, the kingdom was in the long view, and this is what Israel was to have understood.
