First of all, that is a lovely piece of furniture.
Secondly, I wouldn’t be concerned about seeing faces in grains of wood, and certainly not in stimulating paranoia in my mind that something diabolical is attached to my furniture. A lot of very sane, educated, and well-meaning Catholics will see the devil underneath every rock and every pillow, and I think they may be giving too much of their thoughts and their time to such subjects.
As a general rule, said only partially tongue-in-cheek: don’t attribute things in your life to the diabolical until *after *you’ve been unable to restrain yourself from seeing a psychiatrist. Feeling that you’ve slipped into insanity and require medical attention is usually the very least of the sort of thing that accompanies the demonic.
Thirdly, please do feel free check out apologist Trent Horn should you become interested in understanding why Catholics believe in God! You can find many radio shows of his on the main page of this Apostolate.
