When God puts his hand to a man, if he were worthless and useless before, he can make him very valuable. You know the price of an article does not depend so much upon the value of the raw material to begin with—bruised reeds and smoking flax; but by Divine workmanship both these things become of wondrous value. You tell me the bruised reed is good for nothing; I tell you that Christ will take that bruised reed and mend it up, and fit it in the pipes of heaven. Then when the grand orchestra shall send forth its music, when the organs of the skies shall peal forth their deep-toned sounds, we shall ask, “What was that sweet note heard there, mingling with the rest?” And some one shall say, “It was a bruised reed.”
