Pray for a clean heart and sanctify your battle in Christ. Say the following traditional Prayer for Purity as a closing prayer each day:
O my God, thou who hast given me a body to keep pure and clean and healthy for thy service and my eternal happiness, forgive me for all my unfaithfulness in this great responsibility. Forgive me for every mean use which I have made of thy gifts in thought, word or deed since my rebirth as thine own adopted child in Baptism and my registration as a soldier of Jesus on the day of my Confirmation.
Create in me a clean heart, O God, and give me a steadfast will that I may be a strength to others around me. Teach me to reverence my body and the bodies of my fellow creatures. Help me to see the glory of perfect manhood in Jesus Christ and of perfect womanhood in Mary Immaculate. Inspire me with such love for the ideals for which our Savior lived and died, that all my passions and energies will be caught up into the enthusiasm of His service and evil things will lose their power. May my body be the servant of my soul, and may both body and soul be Thy servants, through Christ, our Lord. Amen.
