Deuteronomy 7:8-9

8Instead, it was because of the Lord's love for you. Also, he had made a serious promise to your ancestors and he was faithful to that promise. So he used his great power to bring you out of Egypt, where you were slaves. He rescued you from the power of Pharaoh, Egypt's king.

9Remember that the Lord your God is the only true God. So love him and obey his commands. Then you can trust him to be faithful to his covenant. He made that covenant with you, his people, and with your descendants for ever.
