He whose ear listens to the life-giving reproof will dwell among the wise. He who neglects discipline despises himself, but he who listens to reproof acquires understanding. The fear of the Lord is the instruction for wisdom, and before honor comes humility (Proverbs 15: 31-33).
To accept reproof for our actions or attitude helps us become all we should be or could be in Christ. Reproof in these verses is called "life-giving." In accepting reproof we also acquire understanding and wisdom. "Before honor comes humility," which is the result of the reproof allowed by God for our good and His glory!
