It's not enough to "know" and "understand" things, you also have to be able to apply them to life. Wisdom is the goal, and it doesn't come easy. Being smart and being wise are not the same thing. "In addition to being a wise man, the Preacher also taught the people knowledge; and he pondered, searched out and arranged many proverbs" (Eccl. 12:9). "The tongue of the wise makes knowledge acceptable..." (Prov. 15:2). "The lips of the wise spread knowledge..." (Prov. 15:7).
Israel recognized Solomon's wisdom, "for they saw that the wisdom of God was in him to administer justice" (1 Kings 3:28). The Psalms declare: "The mouth of the righteous utters wisdom" (37:30); "My mouth will speak wisdom" (49:3). Again, the Proverbs support this aspect of learning: "The mouth of the righteous flows with wisdom" (10:3 1); "She opens her mouth in wisdom" (31:26).
Wisdom is the practical application of knowledge and understanding as revealed in Ecclesiastes: "For wisdom is protection just as money is protection. But the advantage of knowledge is that wisdom preserves the lives of its possessors" (7:12); "Wisdom strengthens a wise man more than ten rulers who are in a city" (7:19); "Wisdom is better than strength" (16); "Wisdom is better than the weapons of war" (9:18); "Wisdom has the advantage of giving success" (10:10). You are to have the "word of Christ richly dwell within you, with all wisdom teaching and admonishing one another..." (Col. 3:16); The Scriptures are "able to give you wisdom that leads to salvation through faith which is in Christ Jesus" (2 Tim. 3:15); And we are told, "conduct yourselves with wisdom toward outsiders, making the most of the opportunity" (Col. 4:5).
Genuine understanding is evidenced in obedience to the truth as we see in these passages from Psalms: "A good understanding have all those who do His Commandments" (111: 10); "Give me understanding, that I may observe Thy law, and keep it with all my heart" (119:34); "Give me understanding, that I may learn Thy commandments" (119:73); "From Thy precepts I get understanding; therefore I hate every false way" (119:104). The Proverbs observe: "a man of understanding walks straight" (15:21)."The rich man is wise in his own eyes, but the poor who has understanding sees through him" (28:11).
God complains to Jeremiah, "For My people are foolish. They know Me not; they are stupid children, and they have no understanding. They are shrewd to do evil, but to do good they do not know" (4:22). Daniel and his companions were described as those who were "endowed with understanding, and discerning knowledge" (Dan. 1:4). The apostle John points us to the ultimate purpose of understanding when he writes, "And we know that the Son of God has come, and has given us understanding, in order that we might know Him who is true..." (1 John 5:20).
