Psalm 37 sets forth a pathway of power. It is filled with things to do and not to do.
Look at the times it says "fret not" and at the imperative sentences that begin with "trust," "commit", and "delight."
1Fret not thyself because of evildoers, neither be thou envious against the workers of iniquity.
2For they shall soon be cut down like the grass, and wither as the green herb.
3Trust in the LORD, and do good; so shalt thou dwell in the land, and verily thou shalt be fed.
4Delight thyself also in the LORD: and he shall give thee the desires of thine heart.
5Commit thy way unto the LORD; trust also in him; and he shall bring it to pass.
6And he shall bring forth thy righteousness as the light, and thy judgment as the noonday.
7Rest 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.
8Cease from anger, and forsake wrath: fret not thyself in any wise to do evil.
The progression is simple. It mirrors our growth in the Lord. First we come to a saving faith by believing in him. Trust in the Lord.
Then we get so excited about him that thoughts of him take over our lives. We talk about him constantly and find great joy just being in his presence.
Eventually we learn that all we have is not ours, but his. So we commit our lives and our goods and our business dealings to him.
Eventually we learn to rest patiently in him, knowing that all things will come to fruition in his good time, not on our earthly timetable.
Then we can cease from wrath and anger. Those emotions come when we think someone has spoiled something we were entitled to. We are entitled to nothing but a relationship with God. All else is negotiable.
At that point, we can be still and know that he is the sovereign Lord of all the universe.
Help us to move from belief to trust to commitment to rest in you. Grant that we may be swift students and able practitioners. Help us to cease from all futility and know that you are the sovereign Lord, that we can cease our fretting because you have our best interest at heart.
In Jesus' most precious name.
