How should Christians treat the relevance of Biblical wisdom literature?

James writing to Jews, seems to ignore the value of wisdom literature: >If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him. (James 1:15 ESV) Later he gives a more detailed description of wisdom from above: >13 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. (James 3) With the detailed explanation of wisdom in mind, the earlier statement, *if any of you lacks wisdom* seems rhetorical. Of course, everyone lacks the type of wisdom James describes. So everyone should realize this condition and ask God. Paul makes a similar distinction between the wisdom of God: >For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe. (1 Corinthians 1:21) Paul is explicit, the world did not know God through wisdom. He continues making clear he is speaking of the Gospel which is foolishness to the Greek who seek wisdom (Corinthians 1:22-30). Therefore, in contrast to Judaism who would find wisdom in wisdom books, such as Proverbs and Ecclesiastes, the Christian whose access to God by the Spirit in the name of Jesus, would ask God. How should Christians value the relevance of Old Testament wisdom books?
