My prayers must meet a brazen heaven And fail and scatter all away. Unclean and seeming unforgiven My prayers I scarcely call to pray. I cannot buoy my heart above; Above I cannot entrance win. I reckon precedents of love, But feel the long success of sin. My heaven is brass and iron my earth: Yea, iron is mingled with my clay, So harden'd is it in this dearth Which praying fails to do away. Nor tears, nor tears this clay uncouth Could mould, if any tears there were. A warfare of my lips in truth, Battling with God, is now my prayer.
