Fr. Dan Reehil, exorcist for the Diocese of Nashville, shares who he believes are most vulnerable to demonic attacks. Drawing from years of ministering to the possessed and oppressed, he explains how sensitivity to the spiritual realm, sexual sin outside of marriage, and addictions like pornography can crack the door open to the enemy—and why dabbling in witchcraft or the occult is like hanging a “welcome” sign for demons. At the heart of his message is a sober warning: sin is always an invitation, but repentance, confession, and a life rooted in the sacraments slam that door shut.
