Praying from Hebrews 9:19 relating to sacrifice, law, cleansing

Dear Lord, as we reflect on the words spoken by Moses to your people, we are reminded of the importance of following your commandments. We ask that you help us to live our lives in accordance with your law. Just as Moses took the blood of the calves and goats to sprinkle on the book and the people, we ask that you cover us with your grace and mercy. May we be washed clean of our sins and be made new in your sight. We thank you for your love and forgiveness, and we pray that we may always seek to honor you in all that we do. Amen.
