(3.) It is fit he should manifest his hatred of sin, otherwise he could not be glorified by his creatures, as an holy God; for he cannot have the glory of any attribute ascribed to him, unless there be a visible display thereof; therefore it is necessary to demonstrate his hatred of sin, by punishing it; and, hence an obligation arises from a necessity of nature, and not barely from an act of his will, to bring to condign punishment all sin, even that which he designs to pardon: But this could not have been done without a demand of satisfaction to be given, by a surety, in the sinner’s behalf, which plainly evinces the necessity of satisfaction, which was the thing to be proved. 2. This farther appears, from the punishment threatened by the law of God, which is also necessary. For the understanding of which, let it be considered, (1.) That God cannot but give a law to intelligent creatures, who, as such, are the subjects of moral government, and therefore under a natural obligation to yield obedience to him: But this they could not do, if the law were not given and promulgated. (2.) It was necessary for God to annex a threatning to his law, in which respect punishment would be due to those who violate it, whereby obedience might be enforced, and that fear, which is excited by it, would be an additional motive hereunto; otherwise the sinner would be ready to conclude, that he might go on in his rebellion against God with impunity. (3.) If this law be violated, as it is by sin, the truth of God, as the result of the threatning annexed to it, obliges him to punish it, either in our own persons, or in the person of our Surety, that so the honour of his law might be secured, which he is obliged to vindicate, as it contains a bright display of the glory of his perfections.
