Whether you are dealing with something spiritual right now or not, the one thing that I will point out right before we begin is (as we'll see from God's words) always keep our focus on God!!! He is our only defense. And our loving, everywhere-present, all-knowing, all-powerful God is amazing!!!
When I was little, my mom had spent months making a clown-doll to hang on the wall in my room, right below a sconce. When I saw the clown point at me, repeatedly, I finally had the courage to call out for my mom, begging her to please remove the clown. She was very angry and told me that it was all in my imagination. She had worked so hard to make it!!! But days later, in extreme frustration (because I kept pleading with her), she took the clown away.
Decades later, I mentioned this memory, and she quickly said, "I didn't believe you then, but I do now." In fact, several years after that incident, my parents felt it necessary to go into every corner of every room praying for God to fill the space and remove all evil. Because of someone else, there had been occult activity, which had "invited" a few demons into our home.
Of course, now I know that it was not the clown that was evil. It wasn't the clown that needed to be removed, but the evil spirits that were "visiting" our house.
