These verses describe the miraculous cure of a sick man. A centurion, or officer in the Roman army, applies to our Lord on behalf of his servant, and obtains what he requests. A greater miracle of healing than this, is nowhere recorded in the Gospels. Without even seeing the sufferer, without touch of hand or look of eye, our Lord restores health to a dying man by a single word. He speaks, and the sick man is cured. He commands, and the disease departs. We read of no prophet or apostle, who wrought miracles in this manner. We see here the finger of God.
J. C. Ryle, Luke, Volume 1
