What engagement can be upon us, which these reasons do not reach and answer? The liberty of our persons, and of our estates, is worth much; but the liberty of the gospel and purity of doctrine and ordinances, are worth much more. Peace is a precious jewel, but who can value truth? The wise merchant will sell all that he hath with joy to buy this, and blesses God for the bargain. And because of all this, we are called to make a covenant this day. Truth of doctrine and purity of worship were going, and much of them both were gone. The liberty of our persons, and property of our estates, were going, and much of them both were gone; we were at once growing popish and slavish, superstitious and servile; we were in these great distresses, "And because of all this we make a covenant this day." That these are the grounds of our covenant, is clear in the tenor of the covenant. The preamble whereof speaks thus: "We calling to mind the treacherous and bloody plots, conspiracies, attempts, and practices of the enemies of God, against the true religion and professors thereof, in all places, especially in these three kingdoms, ever since the reformation of religion; and how much their rage, power and presumption are of late, and at this time increased and exercised, whereof the deplorable estate of the church and kingdom of Ireland, the distressed estate of the church and kingdom of England, and the dangerous estate of the church and kingdom of Scotland, are present and public testimonies: we have now at the last, for the preservation of ourselves, and our religion, from utter ruin and destruction, after mature deliberation resolved and determined to enter into a mutual and solemn league and covenant." So then, if we be asked a reason of our covenant, here are reasons, clear reasons, easy to the weakest understanding, yea, open to every man's sense. Who amongst us hath not felt these reasons? and how many have smarted their proof unto us? And as these reasons are so plain, that the most illiterate and vulgar understandings may conceive them; so they are so weighty and cogent, that the most subtile and sublime understandings cannot but be subdued to them; unless, because they are such masters of reason, they have resolved to obey none. And yet where conscience is indeed unsatisfied, we should rather pity than impose, and labour to persuade, rather than violently to obtrude. Now seeing we have all this for the ground of a covenant, let us cheerfully and reverently make a sure covenant, which is the third point in the text, the property of this covenant: we make a sure covenant.
