1. Unity or concord, which is intimated in these figurative promises, that even the wolf shall dwell peaceably with the lamb; men of the most fierce and furious dispositions, who used to bite and devour all about them, shall have their temper so strangely altered by the efficacy of the gospel and grace of Christ that they shall live in love even with the weakest and such as formerly they would have made an easy prey of. So far shall the sheep be from hurting one another, as sometimes they have done (Ezek. xxxiv. 20, 21), that even the wolves shall agree with them. Christ, who is our peace, came to slay all enmities and to settle lasting friendships among his followers, particularly between Jews and Gentiles: when multitudes of both, being converted to the faith of Christ, united in one sheep-fold, then the wolf and the lamb dwelt together; the wolf did not so much as threaten the lamb, nor was the lamb afraid of the wolf. The leopard shall not only not tear the kid, but shall lie down with her: even their young ones shall lie down together, and shall be trained up in a blessed amity, in order to the perpetuating of it. The lion shall cease to be ravenous and shall eat straw like the ox, as some think all the beasts of prey did before the fall. The asp and the cockatrice shall cease to be venomous, so that parents shall let their children play with them and put their hands among them. A generation of vipers shall become a seed of saints, and the old complaint of homo homini lupus—man is a wolf to man, shall be at an end. Those that inhabit the holy mountain shall live as amicably as the creatures did that were with Noah in the ark, and it shall be a means of their preservation, for they shall not hurt nor destroy one another as they have done. Now, (1.) This is fulfilled in the wonderful effect of the gospel upon the minds of those that sincerely embrace it; it changes the nature, and makes those that trampled on the meek of the earth, not only meek like them, but affectionate towards them. When Paul, who had persecuted the saints, joined himself to them, then the wolf dwelt with the lamb. (2.) Some are willing to hope it shall yet have a further accomplishment in the latter days, when swords shall be beaten into ploughshares.
