Prudence is growing in knowledge. It is making the effort to learn something new and using that information or skill, whether you enjoy that skill or not. God describes the prudent in the Bible in book of Proverbs 18:15 "The heart of the prudent getteth knowledge; and the ear of the wise seeketh knowledge." In Proverbs 16:21 its says "The wise in heart shall be called prudent: and sweetness of the lips increaseth learning." Fear causes us to pay attention to what God says, knowing that he is very serious in his blessings and his curisngs.
James 1:5 If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.
