What does Proverbs 8:14 mean?

Contrary to arrogant people who are foolish liars, wisdom offers reliable truth that has powerful effects. This is demonstrated in one way by the comparison in Proverbs 8:10–11. There are things money cannot buy, so wisdom is worth more than precious metals or jewels. And yet, riches are easier to obtain through wisdom. Whether one considers earthly matters or eternal ones, godly wisdom is infinitely more valuable than material wealth (Mark 8:36; Luke 12:19–20).

Jesus is the personification of wisdom. Isaiah 9:6 identifies Him as "Wonderful Counselor" and "Mighty God." As such, He always instructs us to pursue the right path and do the right thing. Because He has infallible insight and sound wisdom, He knows what is best for us and works everything for our good (Romans 8:28–30). Because He has immeasurable strength, He keeps us in His grip (John 10:28), exercises all authority in heaven and earth on our behalf as we spread the gospel (Matthew 28:18–20), and enables us to draw strength from Him in every circumstance.

The apostle Paul testifies in Philippians 4:12–13: "I know how to be brought low, and I know how to abound. In any and every circumstance, I have learned the secret of facing plenty and hunger, abundance and need. I can do all things through him who strengthens me." The godly wisdom possessed by Paul gave him access to strength far beyond what would have been possible otherwise.
