a corner, nor a stone for foundations; but thou shalt be desolate for ever, saith the Lord;"[473] and the realization of the fearful doom proclaimed by an angel come down from Heaven--"Babylon the great is fallen, is fallen," and of the woe uttered by a mighty angel, that "took up a stone like a great millstone, and cast it into the sea, saying, Thus with violence shall that great city Babylon be thrown down, and shall be found no more at all."[474] Even the offers of mercy to the unrenewed are made as the requirements of a mere law. So long as they are unaccepted, they possess the same character. They are tenders of what, when acceded to, would be a covenant; but are not the requirements of a covenant till they be appropriated. When received, they are the duties of both a law and a covenant. For example, the injunction to believe on Jesus, addressed to one in a state of sin, is the command of a law, but not of a covenant, to that individual. If not accepted, it binds to punishment for disregard of it as a law, and the non-acceptance of it is a proposed covenant command. If perfidiously received, it binds to punishment for not obeying it, and for deceitfully professing, by vow or oath, to receive it. Accepted in sincerity and truth, and consequently not by the wicked, but by one born again, it is laid hold on at once as a law and a covenant command;--as a requirement of the immutable law of God, and as a duty of the Everlasting Covenant. Commands addressed to believers are at once, even while inculcated, a law and a covenant requirement. They have acceded to these. Thereafter, such therefore remain not merely a law, but a covenant duty, and as enforcing covenant obligation, fall to be habitually observed.
