James 3 defines worldly wisdom as being proud and self-centred, in contrast to godly wisdom which yields the fruit of the spirit. James 3:13-18
Who is wise and understanding among you? By his good conduct let him show his works in the meekness of wisdom. (14) But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth. (15) This is not the wisdom that comes down from above, but is earthly, unspiritual, demonic. (16) For where jealousy and selfish ambition exist, there will be disorder and every vile practice. (17) But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, impartial and sincere. (18) And a harvest of righteousness is sown in peace by those who make peace.
Grounding in God’s word is vital for us to be wise and understanding. Proverbs 9:10
The fear of the LORD is the beginning of wisdom, and the knowledge of the Holy One is insight.
So fear of the LORD is vital and knowledge essential. Knowledge of other things can be useful; a doctor’s knowledge for example if we are sick. But if knowledge of any kind leads us to be proud, that is worldly wisdom. Godly wisdom translates into actions done in love and humility. Even knowledge about God, if driven by pride, is worldly wisdom. The world is full of proud people who have developed great knowledge and wealth. Their end will be the grave. Godly wisdom is not considered valuable and is very rare. We look forward to the time when godly wisdom will be eagerly sought:
Isaiah 2:3 Many peoples shall come, and say: “Come, let us go up to the mountain of the LORD, to the house of the God of Jacob, that he may teach us his ways and that we may walk in his paths.” For out of Zion shall go the law, and the word of the LORD from Jerusalem.
