The uses of Christ's fasting these forty days I find chiefly to be two: The first, to witness to the world the dignity and excellence of His vocation, which Christ, after His baptism, was to take upon Him openly; the other, to declare that he entered into battle willingly for our cause, and does, as it were, provoke his adversary to assault Him: altho Christ Jesus, in the eternal counsel of His Father, was appointed to be the Prince of Peace, the angel (that is, the messenger) of His testament, and He alone that could fight our battles for us, yet He did not enter in execution of it, in the sight of men, till He was commended to mankind by the voice of His heavenly Father; and as He was placed and anointed by the Holy Ghost by a visible sign given to the eyes of men. After which time He was led to the desert, and fasted, as before is said; and this He did to teach us with what fear, carefulness, and reverence the messengers of the Word ought to enter on their vocation, which is not only most excellent (for who is worthy to be God's ambassador?) but also subject to most extreme troubles and dangers. For he that is appointed pastor, watchman, or preacher, if he feed not with his whole power, if he warn and admonish not when he sees the snare come, and if, in doctrine, he divide not the Word righteously, the blood and souls of those that perish for lack of food, admonition, and doctrine shall be required of his hand. But to our purpose; that Christ exceeded not the space of forty days in His fasting, He did it to the imitation of Moses and Elias; of whom, the one before the receiving of the law, and the other before the communication and reasoning which he had with God in Mount Horeb, in which He was commanded to anoint Hazael king over Syria, and Jehu king over Israel, and Elisha to be prophet, fasted the same number of days. The events that ensued and followed this supernatural fasting of these two servants of God, Moses and Elias, impaired and diminished the tyranny of the kingdom of Satan. For by the law came the knowledge of sin, the damnation of such impieties, specially of idolatry, and such as the devil had invented; and, finally, by the law came such a revelation of God's will that no man could justly afterward excuse his sin by ignorance, by which the devil before had blinded many. So that the law, altho it might not renew and purge the heart, for that the Spirit of Christ Jesus worketh by faith only, yet it was a bridle that did hinder and stay the rage of external wickedness in many, and was a schoolmaster that led unto Christ. For when man can find no power in himself to do that which is commanded, and perfectly understands, and when he believes that the curse of God is pronounced against those that abide not in everything that is commanded in God's law to do them--the man, I say, that understands and knows his own corrupt nature and God's severe judgment, most gladly will receive the free redemption offered by Christ
