Nanci and I love The Valley of Vision, which is a collection of brief and profound Puritan prayers compiled by Arthur Bennett (I love the leather edition linked to. It’s one of the few books worthy of having in leather!). We find them powerful and penetrating.
Here’s one I appreciated:
O God, most high, most glorious, the thought of Your infinite serenity cheers me, for I am toiling and moiling, troubled and distressed, but You are for ever at perfect peace. Your designs cause You no fear or care of unfulfilment, they stand fast as the eternal hills. Your power knows no bond, Your goodness no stint. You bring order out of confusion, and my defeats are Your victories: The Lord God omnipotent reigneth.
I come to You as a sinner with cares and sorrows, to leave every concern entirely to You, every sin calling for Christ's precious blood; revive deep spirituality in my heart; let me live near to the great Shepherd, hear His voice, know its tones, follow its calls. Keep me from deception by causing me to abide in the truth, from harm by helping me to walk in the power of the Spirit. Give me intenser faith in the eternal verities, burning into me by experience the things I know; Let me never be ashamed of the truth of the gospel, that I may bear its reproach, vindicate it, see Jesus as its essence, know in it the power of the Spirit.
Lord, help me, for I am often lukewarm and chill; unbelief mars my confidence, sin makes me forget You. Let the weeds that grow in my soul be cut at their roots; grant me to know that I truly live only when I live to You, that all else is trifling. Your presence alone can make me holy, devout, strong and happy. Abide in me, gracious God.
