3. Take heed of dallying with this covenant. It is more than serious, a sacred covenant. It is very dangerous jesting with edged tools. This covenant is as keen as it is strong. Do not play fast and loose with it, be not in and out with it; God is an avenger of all such: He is a jealous God, and will not hold them guiltless, who thus take His name in vain. They who swear by, or to the Lord, and swear by Malcham, are threatened to be cut off. To be on both sides, and to be on no side; neutrality and indifferency differ little, either in their sin or danger. 4. Above all, take heed of apostatizing from, or an utter desertion of, this covenant. To be deserted of God, is the greatest punishment, and to desert God, is the greatest sin. When you have set your hands to the plough, do not look back: remember Lot's wife. Besides the sin, this is, _First_, Extremely base and dishonourable. It is one of the brands set upon those Gentiles whom "God had given up to a reprobate mind, and to vile affections," that they were covenant breakers. And how base is that issue which is begotten between, and born from vile affections, and a reprobate mind? where the parents are such, it is easy to judge what the child must be. _Second_, Besides the sin and the dishonour, this is extremely dangerous and destructive. We are said in the native speaking, to cut a covenant, or to strike a covenant, when we make it; and if we break the covenant when we have made it, it will both strike and cut us, it will kill and slay us. If the cords of this covenant do not bind us, the cords of this covenant will whip us; and whip us, not as with cords, but as with scorpions. The covenant will have a quarrel with, and sends out a challenge unto such breakers of it, for reparation. And (if I may so speak) the great God will be its second. As God revenges the quarrel of His own covenant, so likewise the quarrel of ours. He hath already "Sent a sword to revenge the quarrel of His covenant." He will send another to revenge the quarrel of this upon the wilful violators of it. Yea, every lawful covenant hath a curse always waiting upon it, like a marshal or a sergeant, to attack such high contemners of it. It was noted before from the ceremony of killing, dividing, and passing between the divided parts of a beast, when covenants were made, that the imprecation of a curse upon the covenanters was implied, in case they wilfully transgressed or revolted from it. Let the transgressors of, and revolters from this covenant, fear and tremble at the same curse, even the curse of a dreadful division: "That God will divide them and their posterity in Jacob, and scatter them in our Israel; yea, let them fear, that God will rebuke them, and they shall flee far off, and shall be chased as the chaff of the mountains before the wind, and like a rolling wind before the whirlwind. This is (their portion, and) the portion of them that spoil us, and the lot of them that rob us." And if so, is not
