We pray, give us such an awareness of your mercies, that with truly thankful hearts we may show forth your praise, not only with our lips, but in our lives, by giving up ourselves to your service, and by walking before you in holiness and righteousness all our days; through Jesus Christ our Lord, to whom, with you and the Holy Spirit, be honor and glory throughout all ages. Amen.
