There are four things I shall persuade you unto in pursuance of your covenant. 1. To be humbled for your own sins, and for the sins of the kingdom; and more especially, because we have not, as we ought, valued the inestimable benefit of the gospel, that we have not laboured to receive Christ in our hearts, nor to walk worthy of Him in our lives, which are the causes of other sins and transgressions so much abounding amongst us. Gospel sins are greater than legal sins, and will bring gospel curses, which are greater than legal curses. And therefore let us be humbled according to our covenant, for all our gospel abominations. 2. You must be ambitious to go before one another in an example of real reformation. You must swear vainly no more, be drunk no more, break the Sabbath no more. You must remember what David says. "But unto the wicked God saith, What hast thou to do to take My covenant in thy mouth? Seeing thou hatest instruction, and castest My words behind thee." To sin willingly, after we have sworn not to sin, is not only to sin against a commandment, but to sin against an oath, which is a double iniquity, and will procure a double damnation. And he that takes a covenant to reform, and yet continueth unreformed, his covenant will be unto him as the bitter water of jealousy was to the woman guilty of adultery, which made her belly to swell, and thigh to rot. 3. You must be careful to reform your families, according to your covenant, and the example of Jacob and Joshua, and the godly kings fore-mentioned. 4. You must endeavour, according to your places and callings, to bring the churches of God in the three kingdoms to the nearest conjunction, and uniformity in religion. O blessed unity! how comes it to pass, that thou art so much slighted and contemned? Was not unity one of the chief parts of Christ's prayer unto His Father, when He was here upon the earth? Is not unity amongst Christians one of the strongest arguments to persuade the world to believe in Christ? Is it not the chief desire of the holy apostles, that we "should all speak the same things, and that there should be no division amongst us?" Is not unity the happiness of heaven? Is it not the happiness of a city, to be at unity with itself? "Is it not a good and pleasant thing for brethren to dwell together in unity?" How comes it to pass then that this part of the covenant is so much forgotten? The Lord mind you of it this day; and the Lord make this great and famous city, a city of holiness, and a city of unity within itself: for if unity be destroyed, purity will quickly also be destroyed. The church of God is _Una_, as well as _Sancta_; it is but one church, as well as it is a holy church. And "Jesus Christ gave some to be apostles, etc. till we all come to the unity of the faith." The government of Christ is appointed for keeping the church in unity, as well as purity. These things which God hath joined together, let no man put asunder. That
