For in order that neither at the denunciations of punishment any men should despair and become more hardened, nor by the promises of good things be rendered causelessly more remiss, He remedies both these evils, by that which I have before mentioned, saying in this way: Though I should threaten, do not despair; for thou art able to repent, and to reverse the denunciation, like the Ninevites. Though I should promise any good thing, grow not remiss because of the promise. For shouldest thou appear unworthy, the fact of my having promised will not advantage thee, but will rather bring punishment. For I promise thee being worthy.
