God's promises and our responsibilities
When Abram was 99 years old, God made a covenant with him.
God's promise was to make Abram greatly prosperous,
to make him the ancestor of many nations,
to change his name from "Abram" (meaning: great father) to "Abraham" (father of nations),
to give him many descendants who would become many nations,
to have many kings come from his descendants,
and that God would be the God of Abraham and his descendants.
The responsibility of Abraham and his descendants
was to keep God's covenant for generations to come.
(Genesis 17:1-9).
