In the law, God sets forth what a man ought to be, and pronounces a curse upon him if he _is_ not that. But then a man finds, when he looks at himself in the light of the law, that he actually is the very thing which the law condemns. How then is he to get life by it? It proposes life and righteousness as the ends to be attained by keeping it; but it proves, at the very outset, that we are in a state of death and unrighteousness. We want the very things at the beginning which the law proposed to be gained at the end. How, therefore, are we to gain them? In order to _do_ what the law requires, I must have life; and in order to _be_ what the law requires, I must have righteousness; and if I have not both the one and the other, I am "cursed." But the fact is, I have neither. What am I to do? This is the question. Let those who "desire to be teachers of the law" furnish an answer. Let them furnish a satisfactory reply to an upright conscience, bowed down under the double sense of the spirituality and inflexibility of the law and its own hopeless carnality. The truth is, as the apostle teaches us, "the law entered that the offense might abound." (Rom. v. 20.) This shows us very distinctly the real object of the law. It came in by the way in order to set forth the exceeding sinfulness of sin. (Rom. vii. 13.) It was, in a certain sense, like a perfect mirror let down from heaven to reveal to man his moral derangement. If I present myself with deranged habit before a mirror, it shows me the derangement, but does not set it right. If I measure a crooked wall with a perfect plumb-line, it reveals the crookedness, but does not remove it. If I take out a lamp on a dark night, it reveals to me all the hindrances and disagreeables in the way, but it does not remove them. Moreover, the mirror, the plumb-line, and the lamp do not _create_ the evils which they severally point out; they neither _create_ nor _remove_, but simply _reveal_. Thus it is with the law; it does not create the evil in man's heart, neither does it remove it; but, with unerring accuracy, it reveals it.
