Proverbs 20:6

Many a man proclaims his own loyalty and goodness, but who can find a faithful and trustworthy man? The righteous man who walks in integrity and lives life in accord with his (godly) beliefs- how blessed (happy and spiritually secure) are his children after him (who have his example to follow).

People can recognize faithful and trustworthy people by their actions and deeds. There is a blessing that follows a person as they walk uprightly before the Lord. Our children will see our lives and learn from our example, seeing how our trust in the Lord has caused us to prosper.
