"In you, O LORD, do I take refuge; let me never be put to shame; in your righteousness deliver me! Incline your ear to me; rescue me speedily! Be a rock of refuge for me, a strong fortress to save me! For you are my rock and my fortress; and for your name’s sake you lead me and guide me..." —Psalm 31:1–3
Before David prays “be a rock of refuge for me,” he confesses and declares “in you, O LORD, do I take refuge.” The prayers of the psalms, we may even say the prayers of the Bible, are full of confessions and declarations. Such declarations often verge on praise, and no doubt this one is an expression of praise, but on the face it, it is just a statement. A confession.
Such confessions and declarations in prayer are a way of thinking on God with God. This is how we should think on God—prayerfully. Say your prayers with confessions of truth, but also, say your confessions prayerfully. As John Owen put it this way:
“Meditate of [upon] God with God; that is, when we would undertake thoughts and meditations of God, his excellencies, his properties, his glory, his majesty, his love, his goodness, let it be done in a way of speaking unto God, in a deep humiliation and abasement of our souls before him. This will fix the mind, and draw it forth from one thing to another, to give glory unto God in a due manner, and affect the soul until it be brought into that holy admiration of God and delight in him which is acceptable unto him. My meaning is, that it be done in a way of prayer and praise,—speaking unto God.”
Because we don’t declare truth in our prayers, we petition lies in our prayers. Because we don’t confess truth, we pray lies. When you fill your prayers with more declarations and confessions of truth, you will petition your God better in those prayers. Such declarations have a way of pulling us out of our little kingdoms and reorienting our prayers around the kingdom of God.
What David first declares, he then pleas, and then he offers as the grounds for that plea what he has declared. “In you, O LORD, do I take refuge… Be a rock of refuge for me… for you are my rock and fortress” (Psalm 31:1, 2, 3; emphasis mine). Prayer is asking God to be for us what He has said He will be for us because He has said He will be that for us. In your prayers, argue God to God. I believe it was another Puritan author who said something like “God is fond of his own handwriting. Show it to Him.”
