Obeying vs. Relishing

Thomas Chalmers (1780-1847), Free Church Scottish pastor known for his sermon 'The Expulsive Power of a New Affection':

There are a thousand things which, in popular and understood language, man can do. It is quite the general sentiment, that he can abstain from stealing, and lying, and calumny—that he can give of his substance to the poor, and attend church, and pray, and read his Bible, and keep up the worship of God in his family. 

But, as an instance of distinction between what he can do, and what he cannot do, let us make the undoubted assertion, that he can eat wormwood, and just put the question, if he can also relish wormwood. That is a different affair. I may command the performance; but have no such command over my organs of sense, as to command a liking, or a taste for the performance. . . . I may accomplish the doing of what God bids; but have no pleasure in God himself. The forcible constraining of the hand, may make out many a visible act of obedience, but the relish of the heart may refuse to go along with it. . . . 

The poor man has no more conquered his rebellious affections, than he has conquered his distaste for wormwood. He may fear God; he may listen to God; and, in outward deed, may obey God. But he does not, and he will not, love God; and while he drags a heavy load of tasks, and duties, and observances after him, he lives in the hourly violation of the first and greatest of the commandments.
