And having sworn, and entered into this solemn engagement to God and man, make conscience to do accordingly; otherwise it is better thou shouldst not vow. As is said of fasting, "It is not the bowing down of the head for a day;" so of this solemn swearing, It is not the lifting up of the hand for a day, but an honest and faithful endeavouring after the contents of this covenant, all our days. A truce-breaker is reckoned up amongst the vilest of Christians, so a covenant-breaker is listed amongst the worst of heathens, but he that sweareth and changeth not, tho' he swear to his hurt, that is, he that will keep his covenant and oath, tho' the contents of it prove not for him, nay possibly against him, yet he will keep it for his oath's sake, such an one "shall have his habitation with the most High, and dwell in His tabernacle." And as for you, reverend brethren, that are ministers of the gospel, there is yet another obligation will lie upon you: let us look to ourselves, and make provision to walk answerable to this our covenant, for the gospel's sake: it will reflect a great aspersion upon the truth of the gospel, if we should be false or inconstant in any word or purpose, tho' in a matter of less consequence, as you can easily collect from that apology of Paul. How much more in such a case as this is, if we should be found to purpose, nay more, to vow, and covenant, and swear, and all this according unto the flesh, and with us there should be, notwithstanding all these obligations, yea, yea, and nay, nay. That we may all, who take the covenant this day, be constant, immoveable, and abound in this work of the Lord, that we may not start aside, or give back, or go on uncomfortably, there is a twofold grace or qualification to be laboured after.
