Or what king going to make war against another king,.... Our Lord illustrates the same thing, the business of a profession, by another similitude, or parable; taking up a profession of religion, is like to two kings engaging in a war. The king on the one side, is the Christian professor; true believers are kings, they have the apparel of kings, the royal robe of Christ's righteousness; they live like kings, at the table of the King of kings; have the attendance of kings, angels ministering unto them; have crowns and thrones as kings have, and greater than theirs; and have a kingdom of grace now, and are heirs of the kingdom of glory. The king on the other side, is the devil; who is the king and prince of the rest of the devils, and over the men of the world; a kingdom is ascribed to him, which is a kingdom of darkness; and he is said to be a great king, and is represented as proud, cruel, and tyrannical: now the Christian professor's life is a warfare; he is engaged with many enemies; the corruptions of his own heart within, and the world without; and especially Satan, who is to be resisted, and by no means to be yielded to, though there is a great inequality between them: and therefore what man that engages in such a warfare, sitteth not down first, and consulteth whether he be able with ten thousand, to meet him that cometh against him with twenty thousand? and such a difference there is between the Christian professor and the devil; the one is flesh and blood, the other a spirit; the one is raw and undisciplined, the other a veteran soldier; the one a stripling, and the other the strong man armed: their numbers are unequal; the people of Christ are few, and their force and strength in themselves small; and they have a large number of devils, and of the men of the world, and of the lusts of their own hearts, to grapple with; wherefore it is necessary to sit down and consult, not with flesh and blood, but with other Christians; and chiefly, and above all, with God himself; what will be the charges of this warfare; the hardships to be endured; in whose name and strength they are to engage; what weapons to take, and how to use them; and how to get knowledge of the designs, methods, and strength of the enemy, and take every advantage of him.
