What does the Bible say about a faithful man?

Proverbs 28:20 emphasizes the importance of faithfulness by asserting that a faithful man will receive abundant blessings from God and men. In contrast, those who are obsessed with gaining wealth will not be innocent in the eyes of God. This reflects a broader biblical principle—that true faithfulness is marked by steadfastness and integrity before God and others. The text encourages believers to understand that faithfulness is not merely a good quality, but a characteristic of the Lord Jesus Christ, the only truly faithful man.
