Solomon teaches a similar lesson in this proverb. By fearing the Lord, yo admit that you don't have all the answers or often even know the right question to ask. When we put or faith in the Lord, He gives s the foundations we need for wisdom.
Wisdom leads to discernment and good judgment. We do not have to worry about having enough knowledge or wisdom. So long as you are diligent in reading and studying God's Word and having an active relationship with Him, He will give you good judgment and the wisdom you need when the time is right.
