Context

“for, without Christ, all is idolatry and fictitious imaginings of God, whether of the Turkish Koran, of the pope's decrees, or Moses law; if a man think thereby to be justified and saved before God, he is undone. When a man will serve God, he must not look upon that which he does; not upon the work, but how it ought to be done, and whether God has commanded it or no; seeing, as Samuel says, that “God has more pleasure in obedience, than in burnt sacrifices.” Whoso hearkens not to God’s voice, is an idolater, though he performs the highest and most heavy service of God.” source
