5. That the condition of the covenant on our part should be upon such easy terms, therefore it is called a covenant of free grace, and all that God requires of us is to take hold of this covenant; to receive this gift of righteousness; to take all Christ, as He is tendered in the covenant; and, that which is the greatest consolation of all, God hath promised in His covenant to do our part for us. Therefore it is called a testament, rather than a covenant. In the New Testament, the word _diatheke_, is always used by the apostle, and not _syntheke_. Heaven is conveyed into the elect by way of legacy. It is part of God's testament, to write His law in our hearts, and to cause us to walk in His ways. Put these together, seeing there is such infinite mercy in the covenant. A mercy, for God to enter into covenant with us, to do it with us, and not the angels; with us fallen, with us upon, such easy terms, and to make such a covenant that contains so many, and not only so but all blessings here and hereafter, in the womb of it. It must needs be a land-destroying, and soul-destroying sin, to be a covenant-breaker. The use and application of this doctrine is fourfold. 1. Of information. If it be such a land-destroying sin to be a covenant-breaker, let us from hence learn the true cause of all the miseries that have happened unto England in these late years. The womb out of which all our calamities are come--England hath broken covenant with God, and now God is breaking England in pieces, even as a potter breaks a vessel in pieces. "God hath sent His sword to avenge the quarrel of His covenant," as Christ whipped the buyers and sellers out of the temple, with whips made of the cords which they had brought to tie their oxen and sheep withal. A covenant is a cord to tie us to God; and now God hath made an iron whip of that covenant which we have broken asunder, to whip us withal.
