Not what my hands have done     can save my guilty soul; Not what my toiling flesh     has borne can make my spirit whole. Not what I feel or do     can give me peace with God; Not all my prayers and sighs and tears     can bear my awful load. Thy work alone, O Christ,     can ease this weight of sin; Thy blood alone, O Lamb of God,     can give me peace within. No other work, save thine,     no other blood will do; No strength, save that which is divine,     can bear me safely through.                        -- Horatius Bonar
