Trust in the Lord and do good; dwell in the land and enjoy safe pasture. Delight yourself in the Lord and he will give you the desires of your heart. (Psalm 37:3-4)
The land that we are in, is the land that we are in; there is not much we can do to change it. What we can change is how we choose to dwell in that land. We can fret and worry and brood and be frustrated, or we can trust and enjoy and delight and commit. We can try, in futility, to change (or fight) our circumstances, or we can embrace them and change our mindset instead.
The words of this ancient prayer are our invitation to do just that. Eugene Peterson says that, "The Psalms train us in the conversation with God that is prayer." They help us to become all that God desires us to be. So if we take these words and bury them deep in our hearts and souls, and utter them often from our lips, they will begin to take shape and produce fruit within us. They will actually begin to do what they say.
In them we will begin to hear the whisper of the One who made us saying: "Stop fretting and simply enjoy the place where I have put you. You cannot escape it, you might as well embrace it. Delight in me, as I delight in you. Trust me with all that is on your plate and all that is in your heart. I will carry it so that you don't have to. Calm and quiet your soul, even in the midst of the chaos, and find your rest in me."
Believe in the Eternal and do what is good--live in the land He provides; roam, and rest in God's faithfulness. Take great joy in the Eternal! His gifts are coming, and they are all your heart desires. (Psalm 37:3-4, The Voice)
