The 70-year-old man’s “newest” Bible was well-worn, with a tattered cover and discolored pages. It was obviously used often in his final years, but it was hard to find a single pen-mark on any page of the text. After flipping hundreds of pages, I finally found a mark. It was a small circle drawn with black ink around the number “3” in Psalm 141. Of all the verses in this well-read Bible, he had marked this one.
“Set a guard, O Lord, over my mouth; Keep watch over the door of my lips.”
Interesting. 
The verse that this well-studied, 70-year-old Christian man thought so significant to mark and the verse that he wanted to remember was a petition to God to guard his mouth. If he needed that verse, how much more do I need that verse! Not just marked in my Bible but ingrained on my soul! “God, it’s me! I need You to set a guard over my mouth!”
