“The centurion’s faith in the power of Christ he here illustrates by the dominion he had, as a centurion, over his soldiers, as a master over his servants; he says to one, Go, and he goes, etc. They were all at his beck and command, so as that he could by them execute things at a distance; his word was a law to them–dictum factum; well-disciplined soldiers know that the commands of their officers are not to be disputed, but obeyed. Thus could Christ speak, and it is done; such a power had he over all bodily diseases. The centurion had this command over his soldiers, though he was himself a man under authority; not a commander-in-chief, but a subaltern officer; much more had Christ this power, who is the supreme and sovereign Lord of all. The centurion’s servants were very obsequious, would go and come at every the least intimation of their master’s mind. Now, [1.] Such servants we all should be to God: we must go and come at his bidding, according to the directions of his word, and the disposals of his providence; run where he sends us, return when he remands us, and do what he appoints. What saith my Lord unto his servant? When his will crosses our own, his must take place, and our own be set aside. [2.] Such servants bodily diseases are to Christ. They seize us when he sends them; they leave us when he calls them back; they have that effect upon us, upon our bodies, upon our souls, that he orders. It is a matter of comfort to all that belong to Christ, for whose good his power is exerted and engaged, that every disease has his commission, executes his command, is under his control, and is made to serve the intentions of his grace. They need not fear sickness, nor what it can do, who see it in the hand of so good a Friend.”
