The Worldly Wisdom Of The Foolish Man Is Like A Sieve, That Does Alone Retain The Grosser Substance Of The Worthless Bran: But Thou, My Soul, Let Thy Brave Thoughts Disdain So Coarse A Purchase: O Be Thou A Fan To Purge The Chaff, And Keep The Winnow'd Grain: Make Clean Thy Thoughts, And Dress Thy Mixt Desires: Thou Art Heav'n's Tasker, And Thy God Requires The Purest Of Thy Flow'r, As Well As Of Thy Fires.
