To think one will become rich by living humbly never enters the mind of one who truly is. They have no thought of riches and honor as the earned reward for humility. They are humble out of a profound sense of their own poverty. Yet the wisdom of Solomon states the wages of humility are riches, honor, and life.
The Bible says: Proverb 22:4 Humility is the fear of the LORD; its wages are riches and honor and life.
