The Third reason why God will be avenged of those that are covenant-breakers, is: Because that a covenant is the greatest obligation and the most forcible claim that can be invented to tie us to obedience and service. God may justly challenge obedience without covenanting, by virtue of creation, preservation and redemption: He hath made us, and, when lost, He hath purchased us with His blood. But being willing more abundantly to manifest His love, that we be the more fastened to Him, He hath tied Himself to us, and us to Him, by the strong bond of a covenant: as if God should say, Oh ye sons of men! I see you are rebellious and sons of Belial, and therefore, if it be possible, I will make sure. I will engage you unto Me, not only by creation, preservation and redemption, but also by the right of covenant and association. I will make you Mine by promise and oath. And surely he that will break these bonds is as bad as the man possessed with the devil in the gospel, whom no chains could keep fast. When we enter into covenant with God, we take the oath of supremacy, and swear unto Him, that He should be our chief lord and governor, and that we will admit of no sovereign power or jurisdiction, but that God shall be all in all. We likewise take the oath of allegiance, to be His servants and vassals, and that He shall be our supreme in spirituals and temporals. Now, for a Christian that believes there is a God, to break both these oaths of allegiance and supremacy, it is cursed treason against the God of heaven, which surely God will be avenged of. Amongst the Romans, when any soldier was pressed, he took an oath to serve the captain faithfully, and not to forsake him, and he was called _miles per sacramentum_. Sometimes one took an oath for all the rest, and the others only said, the same oath that A.B. took, the same do I. And these were called _milites per conjurationem_. And when any soldier forsook his captain, he had the martial law executed upon him. Thus it is with every Christian: he is a professed soldier of Christ, he hath taken press-money, he hath sworn and taken the sacrament upon it to become the Lord's, he is _miles per sacramentum_, and _miles per conjurationem_: and if he forsake his captain and break covenant, the great Lord of Hosts will be avenged of him, as it is written, "Cursed be the man that obeyeth not the words of the covenant." To break covenant is a sin of perjury, which is a sin of an high nature; and if for oaths the land mourneth, much more for breach of oaths. To break covenant is a sin of spiritual adultery; for by covenanting with God, we do as it were, "join ourselves in marriage to God," as the Hebrew word signifieth. Now, to break the marriage knot is a sin for which God may justly give a bill of divorce to a nation. To break covenant is a sin of injustice; for by our covenant we do enter, as it were, into bond to God, and engage ourselves as a creditor to his debtor; now the sin of injustice is a
