Thanks for the reminder, ConservativeOne! I keep a tiny bowl–a minifont–of holy water on my altar (which is near my bed) and bless myself each morning, or really anytime I feel I need it. Some people think this is superstitious and/or paranoid, but we need to realize our true enemy is spiritual! Hearing stories about exorcisms and exorcists, and hearing from them myself, helps me to remember the persistence of the devil.
I have another tip: blessed salt. You may use it to cook for healing purposes. Remember, with God, anything is possible! The other day, my dad’s leg was hurting so bad he could hardly walk. I also had a bad cold, strangely. I put blessed salt in our lunch. The next day, we were both fine! A beautiful sacramental, a very functional reminder that we are salt for the earth.
Another powerful exorcism prayer:
**In the name of Jesus, I bind you any spirit not of the Holy Spirit, and send you to the foot of the cross to be judged by our Lord. **
(except I say “we bind you” because I always picture that it’s Mama Mary and my Guardian Angel doing the job
