Throughout the Bible, we see Our Lord expelling demons and unclean spirits to set people free. Do not despair if there is a "demon" in your life that seems to have a grip on you or an unclean spirit that is preventing you from growth in holiness. They are part of our frail human condition.  

Yet, remember and be convinced that no demon or an unclean spirit is stronger than the Lord's amazing grace, healing love, and saving power. With faith and trust in these gifts, speak to the Lord.  

Tell him specifically the demon and/or unclean spirit you need him to expel. Ask him to set you free so you may spend this day not in the grip of the Evil One but in the merciful and loving embrace of the Lord Our God.
