What does Genesis 17:7 mean?
God continues to describe His covenant promises to the newly renamed Abraham, formerly known as Abram. Already, God has revealed that Abraham will be the father of multiple nations; kings will come from him. Now God makes it clear that these covenant promises will extend to Abraham's offspring throughout all their generations. In fact, God describes this covenant as everlasting. God will be Abraham's God and the God of Abraham's offspring forever. This covenant relationship will never end. God will keep these promises into eternity.In establishing this forever covenant between Abraham's offspring and Himself, God is making for Himself a people of His own, a people set apart as His people. These people will eventually become the nation of Israel.
And yet, despite what Abraham may think, the son who will fulfill these promises has not yet been born. Ishmael, Abraham's son through his servant Hagar (Genesis 16:2; 16:16), was never meant to be the promised son. He will be blessed, and prosperous, as God has promised his mother (Genesis 16:10–12). Instead, God intends to allow this elderly couple to conceive a son, who will be named Isaac (Genesis 17:19).
