Psalm 141: 3-4
Set a guard, O LORD, over my mouth; keep watch over the door of my lips! Do not let my heart incline to any evil, to busy myself with wicked deeds in company with men who work iniquity, and let me not eat of their delicacies!
Lord, only Your Holy Spirit can be the guard of my mouth, direct my heart away for evil and control my appetite for the delicacies of the world. I have proven time and time again, that I am powerless, all too willing to succumb to the siren call of the Evil One. But in You, with You, for You will be goodness and mercy all the days of my life.
