Worry is Satan, grabbing you with vicious teeth and shaking you back and forth until you are totally disoriented. Then batting you around as you stagger in confusion and try to escape the thoughts that are tormenting you. Satan "worries" us the way a cat "worries" a small mouse.
Satan's teeth are thoughts, the concerns/ the worries that grab on to us and won't let go. God's answer is Holy Spirit and Philippians 4:6-7.
