Deuteronomy 4:29-31

29But even in those places, if you look for the Lord your God, you will find him. If you want to serve him with everything that you think and with everything that you do, you will find him.

30When trouble happens to you in the future, you will turn back to him. When all these bad things happen to you, you will obey God again.

31That is because the Lord your God is very kind. So he will not leave you alone. He will never destroy you. He will never forget the covenant that he made with your ancestors. That was a serious promise that he made to them.
