We are at a stand sometimes, why there is so little growth among churches, why men have been so long in learning; and are yet so far from attaining the knowledge of the truth; some have given one reason, and some another; some say pride is the cause, and others say covetousness is the cause. I wish I could say these were no causes; but I observe, that when God entered his controversy with his people of old, he mainly insisted upon some one sin, as idolatry, and shedding innocent blood, &c., as comprehensive of the rest; not but that they were guilty of other sins, but those that were the most capital are particularly insisted on: in like manner, whoever would but take a review of churches that live in contentions and divisions, may easily find that breach of unity and charity is their capital sin, and the occasion of all other sins. No marvel then, that the Scripture saith, the whole law is fulfilled in love: and if so, then where love is wanting, it needs must follow the whole law is broken. It is where love grows cold that sin abounds; and therefore the want of unity and peace is the cause of that leanness and barrenness that is among us; it is true in spirituals as well as temporals, that peace brings plenty. 7. Where unity and peace is wanting, our prayers are hindered; the promise is, that what we shall agree to ask shall be given us of our heavenly Father: no marvel we pray and pray, and yet are not answered; it is because we are not agreed what to have. It is reported that the people in Lacedemonia, coming to make supplication to their idol god, some of them asked for rain, and others of them asked for fair weather: the oracle returns them this answer, That they should go first and agree among themselves. Would a heathen god refuse to answer such prayers in which the supplicants were not agreed, and shall we think the true God will answer them? We see then that divisions hinder our prayers, and lay a prohibition on our sacrifice: “If thou bring thy gift to the altar,” saith Christ, “and there remember that thy brother hath aught against thee, leave thy gift, and go, and first be reconciled to thy brother, and then come and offer it.” So that want of unity and charity hinders even our particular prayers and devotions. This hindered the prayers and fastings of the people of old from finding acceptance; Isa. lviii. 3. The people ask the reason wherefore they fasted, and God did not see nor take notice of them. He gives this reason, Because they fasted for strife and debate, and hid their face from their own flesh. Again, Isa. lix., the Lord saith, his hand was not shortened, that he could not save; nor his ear heavy, that he could not hear: but their sins had separated between their God and them. And among those many sins they stood chargeable with, this was none of the least, viz., that the way of peace they had not known. You see where peace was wanting, prayers were hindered, both under the Old and New Testaments.
