<p>2:16 - see on Job 21:22.</p><p><i>For who has known the mind of the Lord, that he should instruct Him? But we have the mind of Christ</i>- The person who knows the Lord's mind is the one who has His Spirit (:11). We have the mind of Christ, who had the mind of God. The spirit of Christ and that of God are the same thing. The idea that men should instruct God is unthinkable- but this is what effectively is the position of those who consider that their human wisdom is the true wisdom, and God's wisdom is foolishness. The quotation from Is. 40:13,14 is about God's people in Babylon being tempted to think that the wisdom of Babylon, perhaps the most advanced in the world at its time, was somehow superior to that of Israel's God. Paul uses the same idea in Rom. 11:34 concerning the false wisdom of Judaism claiming as it were to be superior to God's wisdom in Christ.</p>
