O God, I have tasted Thy goodness, and it has both satisfied me and made me hunger for more. I am painfully conscience of my need of further grace. I am ashamed of my lack of desire. O God, the triune God, I want to want Thee, I long to be filled with longing; I thirst to made more thirsty still. Show me Thy glory, I pray Thee, that so I may know Thee indeed. Begin in mercy a new work of love in me. Say to my soul, "Rise up, my love, my fair one, and come away."(SoS 2:10) Then give me grace to rise and follow Thee up from this misty lowland where I have wandered so long. In Jesus' name, Amen.
