Lord God, heavenly Father, we give thanks that in your great mercy and compassion you allowed your dear Son to become incarnate and through him redeemed us from sin and eternal death. Enlighten our hearts by your Holy Spirit that we may always be thankful for such grace and be comforted in all trouble and temptation, and at last, obtain eternal salvation; through your beloved Son, Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one true God, now and forever. Amen.
