Lord God, heavenly Father, you allowed your Son, our Lord Jesus Christ, to become fully human and come into the world to destroy the tyranny of the devil. Deliver us poor offenders from sin and death and give us eternal life. Rule and govern our hearts by your Holy Spirit, that we may seek no other refuge than his Word and avoid all offense, that we may always be found among the faithful followers of your Son, and by faith in him 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.
