Set my heart on fire with the love of Thee, most loving Father, and then to do Thy will, and to obey Thy commandments, will not be grievous to me. For to him that loveth, nothing is difficult, nothing is impossible; because love is stronger than death. Oh, may love fill and rule my heart. For then there will spring up and be cherished between Thee and me a likeness of character, and union of will, so that I may choose and refuse what Thou dost. May Thy will be done in me and by me forever—Amen.
Paradise for the Christian Soul.
Most merciful God, the helper of all men, so strengthen us by Thy power, that our sorrow may be turned into joy, and we may continually glorify Thy holy Name; through Jesus Christ our Lord—Amen.
Sarum Breviary, A.D. 1085.
