The know-it-all has nothing to learn. (Antonin Scalia, late US supreme court justice)
He said, “[The] attitude of humility before the breadth of knowledge mankind has accumulated, and before the even greater breadth of the unknown, is the beginning of wisdom.” We’ve all known a “know-it-all.” And we quickly discovered that he or she wasn’t really as knowledgeable as they thought. A little humility would have made it easier to listen and understand.
If you are wise and understand God’s ways, prove it by living an honorable life, doing good works with the humility that comes from wisdom (James 3:13).
