Where to find scriptural help, regarding purity:
Matthew 5: 27-32
You have heard that it was said, ‘Do not commit adultery.’ But I tell you that anyone who looks at a women lustfully has already committed adultery with her in his heart. If your right eye causes you to sin, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. And if your right hand causes you to sin, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell.
Almighty God, whose strength is made perfect in weakness, mortify and kill all vices in me and strengthen me by Your grace that by the innocence of my life and the strengthening of my faith, even unto death, I may glorify Your holy name, through Jesus Christ, Your Son, our Lord,
