Do not fret because of those who are evil or be envious of those who do wrong; for like the grass they will soon wither, like green plants they will soon die away. Trust in the LORD and do good; dwell in the land and enjoy safe pasture. Take delight in the LORD, and he will give you the desires of your heart. Commit your way to the LORD; trust in him and he will do this: He will make your righteous reward shine like the dawn, your vindication like the noonday sun. Be still before the LORD and wait patiently for him; do not fret when people succeed in their ways, when they carry out their wicked schemes. Refrain from anger and turn from wrath; do not fret—it leads only to evil.
This passage is bracketed about with a phrase that touches me to the core, "Do not fret.' I am better at not fretting than I used to be. How about you? Do you fret? A very wise man, who has beaten us to glory, taught me not to fret. I had asked him how come he was so calm. He replied that I ought not to confuse calm with poise. He was the most caring of men; still waters ran deep. He advised that we ought not waste our mental energies on things that probably would not happen. If we did that, we would not have energy left for the things that matter. As he put it, 'most things he worried about when he was young did not come to pass.' And, he went on, 'I'm still here and I can't even remember what I was worried about!'
In case you didn't notice, the phrase 'do not fret,' occurs three times. The psalmist offers a better way forward. Trust and delight in the LORD. Commit your way to the LORD and be still before him.
Prayer. Lord God Almighty, Father, Son and Holy Spirit, help me not to fret. Rather help me to trust in you, and to be delighted in doing so. In Jesus's name. Amen.
