Charles H. Spurgeon on Psalms 5:4

"Thou art not a God that hath pleasure in wickedness." As a man that cutteth with a dull knife is the cause of cutting, but not of the ill-cutting and hacking of the knife —the knife is the cause of that; or if a man strike upon an instrument that is out of tune, he is the cause of the sound, but not of the jarring sound —that is the fault of the untuned strings; or, as a man riding upon a lame horse, stirs him —the man is the cause of the motion, but the horse himself of the halting motion: thus God is the author of every action, but not of the evil of that action —that is from man. He that makes instruments and tools of iron or other metal, he maketh not the rust and canker which corrupteth them, that is from another cause; nor doth that heavenly workman, God Almighty, bring in sin and iniquity; nor can he be justly blamed if his creatures do soil and besmear themselves with the foulness of sin, for he made them good. Spencer's Things New and Old.
