The idea that "experience is the best teacher" is popular—but wrong. Experience alone doesn’t teach wisdom; it only reflects what’s already in the heart. An alcoholic doesn’t become wise by getting drunk, nor does someone become discerning by being hurt. Without faith and a godly heart, experience leads to bitterness, not insight. As Proverbs says, “Keep thy heart with all diligence,” because it’s the heart—not the experience—that shapes what we learn. True wisdom comes not from what we go through, but from how God’s Word and Spirit shape us in it. Experience isn’t the teacher—faith is.
