For both the law and the Gospel are the energy of one Lord, who is "the power and wisdom of God;" and the terror which the law begets is merciful and in order to salvation. "Let not alms, and faith, and truth fail thee, but hang them around thy neck." [2123] In the same way as Paul, prophecy upbraids the people with not understanding the law. "Destruction and misery are in their ways, and the way of peace have they not known." [2124] "There is no fear of God before their eyes." [2125] "Professing themselves wise, they became fools." [2126] "And we know that the law is good, if a man use it lawfully." [2127] "Desiring to be teachers of the law, they understand," says the apostle, "neither what they say, nor whereof they affirm." [2128] "Now the end of the commandment is charity out of a pure heart, and a good conscience, and faith unfeigned." [2129]
