This reminds me of my brother-in-law (now deceased) who claimed to know all needed to be known about the Bible although he never cracked one open. He got his knowledge from shows on the History Channel.
After hearing him spew about something he thought was in the Bible, you knew how the Philistines felt when they were “slain with the jawbone of an ASS.”
I am witnessing to, and praying for, him. He's already 77, and one never knows how much time remains before he takes that same journey. God brought us into each others' orbits two years ago, and I may be his last intervener.
