Here are two sections of William Gurnall’s discussion of “the gospel of peace” (Eph 6:15):
The news which the gospel hath in its mouth to tell us poor sinners is good. It speaks promises, and they are significations of some good intended by God for poor sinners. The law, that brings ill news to town. Threatenings are the ‘lingua vernacula legis’ – the native language of the law. It can speak no other language to sinners but denunciations of evil to come upon them, but the gospel smiles on poor sinners, and plains [smooths] the wrinkles that sit on the law’s brow, by proclaiming promises.
1 Timothy 1:15. This bridge which the gospel lays over the gulf of God’s wrath, for poor sinners to pass from their sins into the favor of God here, and into the kingdom of God hereafter, is supported with no other arches than the wisdom, power, mercy, and faithfulness of God….
