It seems to be one of the hardest things in the world to see accurately the person you spend the most time with, and I’m referring to yourself. It is the Ego, the I, the Me, that not only is evasive and preferring hiding spots, but other times is a very pushy liar. The number of half-truths and shady observations I have told me over the years is quite a piece of work.
There are a number of ways that such illusions can go, but one the Bible often talks about relates to having opinions, especially high opinions about our own importance. For as many wise guys as there are in the world, there are even more wise-in-their-own-eyes guys. Just hit like and subscribe to their channel.
One of my favorite progressions of Proverbs is in chapter 26, which begins with 10 of the first 11 verses describing the damage done by the fool—he deserves a beating, he can’t be trusted with a message, his “wise” words jab others like thorns, he repeats his folly like a dog to vomit—and then verse 12: “Do you see a man who is wise in his own eyes? There is more hope for a fool than for him.”
Paul exhorted the Romans not to think more highly of themselves than they ought to think (Romans 12:3). How can you not be “that guy”? Look into the mirror of God’s Word, remember that you have nothing that you weren’t given by grace, and refuse to believe that you don’t need anyone else; you need the rest of the Body (Romans 12:4-5).
