For example, "Thou shalt not covet," is a precept by which we are all convicted of sin, since no man can help coveting, whatever efforts to the contrary he may make. In order therefore that he may fulfil the precept, and not covet, he is constrained to despair of himself and to seek elsewhere and through another the help which he cannot find in himself; as it is said, "O Israel, thou hast destroyed thyself; but in Me is thine help" (Hosea xiii. 9). Now what is done by this one precept is done by all; for all are equally impossible of fulfilment by us. Now when a man has through the precepts been taught his own impotence, and become anxious by what means he may satisfy the law--for the law must be satisfied, so that no jot or tittle of it may pass away, otherwise he must be hopelessly condemned--then, being truly humbled and brought to nothing in his own eyes, he finds in himself no resource for justification and salvation. Then comes in that other part of Scripture, the promises of God, which declare the glory of God, and say, "If you wish to fulfil the law, and, as the law requires, not to covet, lo! believe in Christ, in whom are promised to you grace, justification, peace, and liberty." All these things you shall have, if you believe, and shall be without them if you do not believe. For what is impossible for you by all the works of the law, which are many and yet useless, you shall fulfil in an easy and summary way through faith, because God the Father has made everything to depend on faith, so that whosoever has it has all things, and he who has it not has nothing. "For God hath concluded them all in unbelief, that He might have mercy upon all" (Rom. xi. 32). Thus the promises of God give that which the precepts exact, and fulfil what the law commands; so that all is of God alone, both the precepts and their fulfilment. He alone commands; He alone also fulfils. Hence the promises of God belong to the New Testament; nay, are the New Testament. Now, since these promises of God are words of holiness, truth, righteousness, liberty, and peace, and are full of universal goodness, the soul, which cleaves to them with a firm faith, is so united to them, nay, thoroughly absorbed by them, that it not only partakes in, but is penetrated and saturated by, all their virtues. For if the touch of Christ was healing, how much more does that most tender spiritual touch, nay, absorption of the word, communicate to the soul all that belongs to the word! In this way therefore the soul, through faith alone, without works, is from the word of God justified, sanctified, endued with truth, peace, and liberty, and filled full with every good thing, and is truly made the child of God, as it is said, "To them gave He power to become the sons of God, even to them that believe on His name" (John i. 12).
