Deuteronomy 4:29-31

But from there you will seek the LORD your God, and you will find Him if you search for Him with all your heart and all your soul. When you are in distress and all these things have come upon you, in the latter days you will return to the LORD your God and listen to His voice. For the LORD your God is a compassionate God; He will not fail you nor destroy you nor forget the covenant with your fathers which He swore to them.
