God finds us when we are faithless. He took Abraham at his worst and made him a blessing to all of the nations, a leader of the people of Israel to do the same, and a key piece in gods own story. God fellowships with us when we've failed. Gods promise doesn't remove all our problems. Gods covenant is unilateral (dependent on one person) and that person is god. The covenant was made right after Abraham lied to pharaoh showing how god fellowships and forgives after we fail. God follows through with us when we forget him. When Israel forgot about god while worshiping the golden calf god remained with them and followed through on his promise. When they were exiled god did not leave or forsake them. He rose up a prophet to talk to them.
