Pray for a Pure Heart

O God Almighty, Father of our Lord Jesus Christ, Thine only begotten Son, give me a body unstained, a pure heart, a watchful mind, and an upright understanding, and the presence of Thy Holy Spirit, that I may obtain and ever hold fast to an unshaken faith in Thy Truth, through Jesus Christ, Thy Son, our Lord; through whom be glory to Thee in the Holy Ghost, forever and ever. Amen.

O God, the Father of our Saviour Jesus Christ, whose name is great, whose nature is blissful, whose goodness is inexhaustible, God and Ruler of all things, who art blessed forever; before whom stand thousands and thousands, and ten thousand times ten thousand, the hosts of holy angels and archangels; sanctify, O Lord, our souls and bodies and spirits, search our consciences, and cast out of us every evil thought, every base desire, all envy and pride, all wrath and anger, and all that is contrary to Thy holy will. And grant us, O Lord, Lover of men, with a pure heart and contrite soul, to call upon Thee, our holy God and Father who art in heaven. Amen.

Grant me, even me, my dearest Lord, to know Thee, and love Thee, and rejoice in Thee. And, if I cannot do these perfectly in this life, let me at least advance to higher degrees every day, till I can come to do them in perfection. Let the knowledge of Thee increase in me here, that it may be full hereafter. Let the love of Thee grow every day more and more here, that it may be perfect hereafter; that my joy may be great in itself, and full in Thee. I know, O God, that Thou art a God of truth, O make good Thy gracious promises to me, that my joy may be full. Amen
