Psalms are prayers that have been prayed by the people of God for millennia, and as such, we ought to continue in that tradition. One of the most unique aspects of being human is our ability to use tools. And “prayers are tools.” But there’s one important clarification: “Prayers are not tools for doing or getting [as we’re used to in our Western culture], but for being and becoming… At the center of the whole enterprise of being human, prayers are the primary technology. Prayers are tools that that God uses to work his will in our bodies and souls. Prayers are tools that we use to collaborate in his work with us.” (Eugene Peterson — ‘Answering God’).
“Perseverance is not the result of our determination, it is the result of God’s faithfulness. We survive in the way of faith not because we have extraordinary stamina but because God is righteous, because God sticks with us. Christian discipleship is a process of paying more and more attention to God’s righteousness and less and less attention to our own; finding the meaning of our lives not by probing our moods and motives and morals but by believing in God’s will and purposes; making a map of the faithfulness of God, not charting the rise and fall of our enthusiasms. It is out of such a reality that we acquire perseverance.” — Peterson, Eugene H.. A Long Obedience in the Same Direction (pp. 126-127). InterVarsity Press. Kindle Edition.
