Deuteronomy 4:31 For the Lord your God is a merciful God; He will not abandon or destroy you (The Lord declares His faithfulness to us even though He knows we will not be faithful to Him, even though He knows we will grow cold toward Him, even though He knows beforehand how our commitment will fade. He remains faithful even in the face of our unfaithfulness. Instead of shaking us off, instead of abandoning us, He chooses to embrace us in forgiveness. He doesn't punish us or hold resentments against us, but instead forgives us freely.) or forget the covenant with your ancestors, which He confirmed to them by oath.
(That same covenant still extends to us today,
a covenant of love and commitment,
a compact of peace and salvation
based on God's Own vow that He swore by Himself that He would be our God and we would be His people.
In those times He knows when we will need Him,
in those times He knows we will have strayed and turned away from Him and from our commitment to Him, even then, still, even then, He does not forget about us or turn away from us when we do finally become desperate enough to return to Him.)
