Prayer for help in moral courage day to day

Guardian of virgins, and holy father Joseph, to whose faithful custody Christ Jesus, Innocence itself, and Mary, Virgin of virgins, were committed; I pray and beseech you, by these dear pledges, Jesus and Mary, that, being preserved from all uncleanliness, I may with spotless mind, pure heart and chaste body, ever serve Jesus and Mary most chastely all the days of my life. Amen.
