1. Where unity and peace is wanting, there is much precious time spent to no purpose. How many days are spent, and how many fruitless journeys made to no profit, where the people are not in peace? how often have many redeemed time (even in seed-time and harvest) when they could scarce afford it, to go to church, and, by reason of their divisions, come home worse than they went, repenting they have spent so much precious time to so little benefit? How sad is it to see men spend their precious time, in which they should work out their salvation, in labouring, as in the fire, to prove an uncertain and doubtful proposition, and to trifle away their time, in which they should make their calling and election sure, to make sure of an opinion, which, when they have done all, they are not infallibly sure whether it be true or no, because all things necessary to salvation and church-communion are plainly laid down in scripture, in which we may be infallibly sure of the truth of them; but for other things that we have no plain texts for, but the truth of them depends upon our interpretations, here we must be cautioned, that we do not spend much time in imposing those upon others, or venting those among others, unless we can assume infallibility, otherwise we spend time upon uncertainty. And whoever casts their eyes abroad, and do open their ears to intelligence, shall both see, and to their sorrow hear, that many churches spend most of their time in jangling and contending about those things which are neither essential to salvation nor church-communion; and that which is worse, about such doubtful questions which they are never able to give an infallible solution of. But now where unity and peace is, there our time is spent in praising God; and in those great questions, What we should do to be saved? and, How we may be more holy and more humble towards God, and more charitable and more serviceable to one another?
2. Where unity and peace is wanting, there is evil surmising and evil speaking, to the damage and disgrace, if not to the ruining, of one another; Gal. v. 14, 15. The whole law is fulfilled in one word, "Thou shalt love thy neighbour as thyself. But if you bite and devour one another, take heed you be not consumed one of another." No sooner the bond of charity is broken, which is as a wall about Christians, but soon they begin to make havock and spoil of one another; then there is raising evil reports, and taking up evil reports, against each other. Hence it is that whispering and backbiting proceeds, and going from house to house to blazon the faults and infirmities of others: hence it is that we watch for the haltings of one another, and do inwardly rejoice at the miscarriages of others, saying in our hearts, "ha! ha! so we would have it:" but now where unity and peace is, there is charity; and where charity is, there we are willing to hide the faults, and cover the nakedness, of our brethren. "Charity thinketh no evil;" 1 Cor. xiii. 5; and therefore it cannot surmise, neither will it speak evil.
3. Where unity and peace is wanting, there can be no great matters enterprised--we cannot do much for God, nor much for one another; when the devil would hinder the bringing to pass of good in nations and churches, he divides their counsels (and as one well observes), he divides their heads, that he may divide their hands; when Jacob had prophesied of the cruelty of Simon and Levi, who were brethren, he threatens them with the consequent of it; Gen. xlix. 7, "I will divide them in Jacob, and scatter them in Israel." The devil is not to learn that maxim he hath taught the Machiavellians of the world, Divide et impera; divide and rule. It is an united force that is formidable. Hence the spouse in the Canticles is said to be but one, and the only one of her mother; Cant. vi. 9. Here upon it is said of her, ver. 10, "That she is terrible as an army with banners." What can a divided army do, or a disordered army that have lost their banners, or for fear or shame thrown them away? In like manner, what can Christians do for Christ, and the enlarging of his dominions in the world, in bringing men from darkness to light, while themselves are divided and disordered? Peace is to Christians as great rivers are to some cities, which (besides other benefits and commodities) are natural fortifications by reason whereof those places are made impregnable; but when, by the subtilty of an adversary or the folly of the citizens, these waters come to be divided into little petty rivulets, how soon are they assailed and taken? Thus it fares with churches, when once the devil or their own folly divides them, they will be so far from resisting of him, that they will be soon subjected by him.
