Psalm 37 - Four ingredients for true happiness
Psalm 37:3-7 Trust in the LORD, and do good; so shalt thou dwell in the land, and verily thou shalt be fed. (4) Delight thyself also in the LORD; and he shall give thee the desires of thine heart. (5) Commit thy way unto the LORD; trust also in him; and he shall bring it to pass. (6) And he shall bring forth thy righteousness as the light, and thy judgment as the noonday. (7) Rest in the LORD, and wait patiently for him: fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass.
Luther called this Psalm a 'garment for the godly' and wrote an inscription of it saying, 'here is the patience of the saints'.
The context of these directions are how verses 1 and 2 tell us to not fret or be envious of the wicked. What are we to do instead? We see here four ingredients or directions involved:
Trust (and do good)
Trust: This is like how Proverbs 3:5-6 says, 'Trust in the LORD with all thine heart; and lean not unto thine own understanding. (6) In all thy ways acknowledge him, and he shall direct thy paths'. Our faith is an alive and active faith which, although does not bring about (for by grace are we saved through faith) or add to our salvation, but proves it as God gives us the grace to do good works.
Delight: Nehemiah 8:10 says, 'the joy of the LORD is your strength', so consider how you are able to look back at past mercies and then look forward in delight.
Commit: This can be said as to roll your works over to God, and this covers all affairs of life.
Rest: This implies a silence and even a calmness as it also says to wait patiently, similar to how Psalm 46:10 tells us to 'Be still, and know that I am God'.
