Deuteronomy 4:29-31

But from there you will search again for the LORD your God. And if you search for him with all your heart and soul, you will find him. “In the distant future, when you are suffering all these things, you will finally return to the LORD your God and listen to what he tells you. For the LORD your God is a merciful God; he will not abandon you or destroy you or forget the solemn covenant he made with your ancestors.
