That we Must Offer Ourselves and All That is Ours, to God and Pray for All

Lord, all things are Yours that are in heaven and upon earth.  I desire to offer up myself to You as a voluntary oblation, and to remain forever Yours.  Lord, in the simplicity of my heart, I offer myself to You this day, as Your servant for evermore, for Your homage, and for a sacrifice of perpetual praise....Deal with me according to Your goodness, not according to my impiety and wickedness....Take, O Lord, from our hearts all suspicion, indignation, anger, and contention, and whatever else may wound charity and lessen brotherly love.  Have mercy, O Lord, have mercy on those that crave Your mercy; give grace to the needy; and grant us so to live that we may be worthy to enjoy Your grace, and that we may attain life everlasting.
