Who Needs Wisdom?

So, who needs wisdom? According to Proverbs 1:4-5, wisdom is needed by everyone--not only those who are simple/young but also those who have already obtained some amount of wisdom:

to give prudence to the simple,
knowledge and discretion to the youth—
Let the wise hear and increase in learning,
and the one who understands obtain guidance (ESV)

Lest we fool ourselves into believing that we are already wise enough, the Scriptures warn us against trusting in our own "wisdom", which isn't truly wisdom at all:

Woe to those who are wise in their own eyes,
and shrewd in their own sight! (Isaiah 5:21, ESV)

This means that we must forsake our pride and self-sufficiency. We must not seek to be wise by our own standards or the standards of the world; instead, we must look to God's wisdom. We are only wise to the extent that we have aligned ourselves to God and His wisdom:

The fear of the Lord is the beginning of wisdom;
all those who practice it have a good understanding.
His praise endures forever! (Psalm 111:10, ESV)
