The answer to the statement is found right here in the verse below.
Proverbs 16:20 He who heeds the word wisely will find good, And whoever trusts in the LORD, happy is he.
It has to do with the Word of God and the Lord.
First of all, we are told that the person who heeds the Word wisely, will find good. To heed the Word wisely, means, "those who listen to instruction" God gives us instruction through His Word, and we can listen to it by simply reading it, being in the Word regularly, etc, etc. Wisely, means, to give attention to, to consider and to ponder. The net result is that we find good in our lives. Or you will find what is pleasant, agreeable, beautiful, and prosperity. Those are all good things by definition.
Secondly, we are told that whoever trusts in the LORD, happy is he. I'm glad it says "whoever" because that opens the door for me, for you, and in truth for anyone, there is no one who cannot trust in the LORD. Because we all have a measure of faith.
LORD, is Jehovah, which means "the existing one" We can trust Him, we can have confidence in Him, we can hope in Him. And, what happens as a by-product of that trust, is that we find ourselves being happy, or blessed. Interestingly enough the word happy here, comes from a word meaning "to be straight, to be level, right, to go forward, relieve" Again, those all resonate with my soul. I enjoy being happy.
Lord, we thank You for your Word. May we take heed to Your Word, and receive Your instruction into our hearts and lives. And, thank You that we can rely upon You, we don't have to go it alone down here, trusting in ourselves, but we can put our confidence in You. Bring that happiness into our lives today, we enjoy the blessings that You bring.
In Jesus name. Amen.
