Deuteronomy 4:29-31

But from thence ye shall seek Jehovah thy God, and thou shalt find him, when thou searchest after him with all thy heart and with all thy soul. When thou art in tribulation, and all these things are come upon thee, in the latter days thou shalt return to Jehovah thy God, and hearken unto his voice: for Jehovah thy God is a merciful God; he will not fail thee, neither destroy thee, nor forget the covenant of thy fathers which he sware unto them.
