"Trust in the Lord and do good; dwell in the land and enjoy safe pasture." (Psalm 37:3)
Psalm 37 is a wisdom psalm, one of the longer acrostic compositions in the Psalter, and its opening advice is given twice for emphasis: do not fret because of those who are evil or be envious of those who do wrong. The fretting and the envy are understandable. The wicked prosper. They seem to get away with everything. They green like flourishing grass and thrive like well-watered plants. And then they wither and vanish like grass cut down, like smoke that dissipates. The long perspective of wisdom sees the end of the wicked as well as their present flourishing, and this changes how their success looks.
The positive commands that follow the "do not fret" are a summary of the life of trust: trust in the Lord and do good, take delight in the Lord, commit your way to the Lord, be still before him and wait patiently. The sequence is important: trust first, then delight, then commit, then wait. The person who has not trusted cannot delight. The person who has not committed cannot wait patiently. Each step makes the next one possible.
But the meek will inherit the land and enjoy peace and prosperity. Jesus quotes this verse directly in the Beatitudes: blessed are the meek, for they will inherit the earth. The meek person is not the passive, spineless person who gets walked over. The Hebrew word anav describes the person who is humble before God, who does not press their own claims or demand their own way, who waits for God to act on their behalf. This person inherits the earth not by taking it but by receiving it. They are strong enough to wait and humble enough to receive.
Brothers and sisters, if you are fretting today about someone who seems to prosper by wrongdoing, Psalm 37 has a prescription. Not an argument. Not a plan. A practice: trust in the Lord and do good. Delight yourself in the Lord. Commit your way to him. Be still and wait patiently. These are not easy instructions. They are the most demanding things you can do when injustice surrounds you. But they are the way of the one who will still be standing when the wicked grass has withered.
Lord God, we commit our way to you and trust in you to act. We take delight in you and rest in your faithfulness. When the wicked prosper and we are tempted to fret, be still our anxious hearts. Give us the meekness that waits and the trust that does not envy. Through Christ our Lord. Amen.
