Psalm 37 contrasts the wicked and the righteous, their way of life and destiny. Both receive a reward appropriate to their way of life. David writes this Psalm as encouragement, “fret not yourself because of evildoers…they will soon fade like the grass“. Instead, “Trust in the Lord, and do good… commit your way to the Lord…refrain from anger.“
The righteous have an inheritance to look forward to, “those who wait for the Lord shall inherit the land“, but have little now “better is the little that the righteous has than the abundance of many wicked“.
We have a refuge from the cares of this life, a God who can deliver us from anything the world does to us. “The salvation of the righteous is from the Lord; he is their stronghold in the time of trouble… he delivers them from the wicked and saves them, because they take refuge in him“.
