We come now to the third kind of peace, which I called a peace of love and unity. A heavenly grace this is, whereby the minds and hearts of men, that even now jarred and rang backwards are made tunable each to other; so as to chime all in to an harmonious consent and concord among themselves. Thus peace in Scripture is frequently taken, as you may see, Mark 9:50; Heb. 12:14; I Thes. 5:13. Now the gospel is a ‘gospel of peace,’ if taken in this notion also, which we shall briefly speak to from this note.
The gospel alone can knit the hearts of men in solid peace
The doctrine we lay down is, that the gospel, and only the gospel, can knit the hearts and minds of men together in a solid peace and love. This, next the reconciling us to God and ourselves, is especially designed by Christ in the gospel; and truly those [blessings] without this, would not fill up the saint's happiness; except God should make a heaven for every Christian by himself to live in. John Baptist’s ministry, which was as it were the preface to and brief contents of, the gospel, was divided into these two heads, ‘To turn many of the children of Israel to the Lord their God,’ Luke 1:16, and ‘to turn the hearts of the fathers to the children,’ ver. 17; that is, to make them friends with God and one another. This is the natural effect of the gospel, where it is powerfully and sincerely embraced—to unite and endear the hearts of men and women in love and peace together, how contrary soever they were before. This is the strange metamorphosis, which the prophet speaks shall be under the gospel, ‘The wolf shall dwell with the lamb, and the leopard shall lie down with the kid,’ Isa. 11:6. That is, men and women, between whom there was a great feud and enmity as betwixt those creatures, they shall yet sweetly agree, and lie in one another’s bosoms peaceably. And how all this, but by the efficacy of the gospel on their hearts? So ‘for the earth shall be full of the knowledge of the Lord,’ ver. 9. Indeed it is in the dark when men fight, and draw upon one another in wrath and fury. If gospel light comes once savingly in, the sword will soon be put up. The sweet spirit of love will not suffer these doings where he dwells; and so peculiar is this blessing to the gospel, that Christ appoints it for the badge and cognizance by which not only they should know one another, but [by which] even strangers should be able to know them from any other sect and sort of men in the world, John 13:35. ‘By this shall all men know that ye are my disciples, if ye have love one to another.’ A nobleman's servant is known as far as he can be seen, by the coat on his back, whose man he is; so, saith Christ, shall all men know you, by your mutual love, that you retain to me and my gospel. If we would judge curiously of wine, [as to] what is its natural relish, we must taste of it, before it comes into the huckster’s hands, or after it is refined from its lees. So, the best way to judge of the gospel and the fruit it bears, is to taste of it, either when it is professed and embraced, with most simplicity—and that was without doubt in the first promulgation—or, secondly, when it shall have its full effect on the hearts of men, and that is in heaven. In both these, though chiefly the last, this peace will appear to be the natural fruit of the gospel.
First. When the gospel was first preached and embraced, what a sweet harmony of peace and admirable oneness of heart was then amongst the holy professors of it, who but a while before were strangers to or bitter enemies one against another! They lived and loved, as if each Christian’s heart had forsaken his own, to creep into his brother’s bosom. They alienated their estates to keep their love entire. They could give their bread out of their own mouths to put it into their brethren’s that were hungry; yea, when their love to their fellow-Christians was most costly and heavy, it was least grudged and felt by them. See those blessed souls, ‘They sold their possessions and goods, and parted them to all men, as every man had need; and they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their bread with gladness and singleness of heart,’ Acts 2:46. More, they are more merry now they have been emptying of their bags by charity, than if they had come from filling them by worldly traffic. So notorious was the love of Christians in the primitive times, that the very heathens would point at them, as Tertullian saith, and say, ‘See how they love one another.’ And therefore, if less love and peace be found now amongst Christians, the blame lies not on the gospel, but on them. The gospel is as peaceful, but they are minùs evangelici—less evangelical, as we shall further show.
Second. Look on the gospel, as at last, in the complement of all in heaven, when the hearts of saints shall be thoroughly gospelized, and the promises concerning the peaceable state of saints have their full accomplishment—then above all this peace of the gospel will appear. Here it puts out and in, like a budding flower in the spring; which one warm day opens a little, and another that is cold and sharp shuts it again. The ‘silence’ in the lower heaven—the church on earth—is but for ‘the space of half an hour,’ Rev. 8:1. Now there is a love and peace among Christians; anon, scandals are given, and differences arise, which drive this sweet spring back; but in heaven it is full blown, and so continues to eternity. There dissenting brethren are made thorough friends, never to fall out. There, not only the wound of contention is cured; but the scar which is here oft left upon the place, is not to be seen on the face of heaven’s peace, to disfigure the beauty of it, which made the German divine so long to be in heaven—where, said he, Luther and Zuinglius are perfectly agreed, though they could not be agreed on earth. But I come to give some particular account how the gospel knits the hearts and minds of men in peace together, and why the gospel alone can do this. While I clear one, I shall the other also.
