There is literally such a thing as feeding on truth; and the place where these spiritual provisions are enjoyed in abundance may well be called the 'banqueting house'. How superior to everything else in the world is the banquet spread for us by Jesus! The truths and doctrines of Scripture, so rich, better than thousands of gold and silver, are the means, sacred vessels brought from heaven, for conveying to us this food of the Spirit. Here we banquet on the riches of redeeming love. The man who feeds on fame, flattery, riches, power, has nothing better than the husks of the dying prodigal; while those who are Christ's share the luxuries of the marriage-supper of the Lamb.
