The great enemy is sin. Sin leads to death. Sin robs joy. Sin ruins relationships. Sin provokes wars. Sin blinds from beauty, makes deaf to truth. Sin also deceives us about us, and this is why worshiping God is so meddlesome. In God’s Word we see His glory, and the more clearly we see His character, the more clear the mirror that shows us our true condition.
We would do almost anything not to get an accurate view on ourselves. Sin loves darkness, sin seeks ambiguity, sin tells lies.
Though he wasn’t a Christian, Richard Feynman was an American physicist well-known for his abilities to learn and to teach. He once said: “The first principle is that you must not fool yourself—and you are the easiest person to fool.”
With divine authority the prophet Jeremiah said, “The heart is deceitful above all things, and desperately sick; who can understand it?” (Jeremiah 17:9) And though as Christians we’ve been given new hearts, we are in the process of becoming less fooled by the flesh. We are in process of better seeing how foolish sin is. We are in process of becoming harder to fool.
The difficulty is not so much having eyes to see, but having the heart to deal with our hearts. When we worship God, we learn what He says, and when we confess, we say the same thing that He says, homologeo. One of the most courageous acts we do every week is to confess our sin. But courageous or not, it is the only way not to be a fool.
