In the next place, let me ask you to think how this story suggests that the true work of God's message is to tear down the veil and to show the ugly thing.
Nathan said unto David, Thou art the man.' It needed a prophet to do that, with divine authority. Nothing less would suffice to get through the thick bosses of the buckler of self-conceit and ignorance which he had to penetrate. As God's messenger, he gathered up, as I said, into one sharp-pointed, keen-edged, steel-bright sentence, the very spirit of the whole ancient Law, which seeks to individualize the sinner, and to drive home to the conscience the consciousness of wrong-doing.
The remarks that I have been making, in the former part of this sermon, imperfect as they must necessarily be, may at least serve one or two purposes in reference to this part of my discourse.
It seems to me that if what I have been saying as to a man's blindness to his own true moral character be at all correct, there flows from that thought a strong presumption in favor of a divine revelation. We need another than our own voice to lay down the law of conduct, and to accuse and condemn the breaches of it. Conscience is not a wholly reliable guide, and is neither an impartial nor an all-knowing judge. Unconsciousness of evil is not innocence. It is not the purest of women who wipes her mouth and says, I have done no harm.' My conscience says to me, It is wrong to do wrong'; but when I say to my conscience, Yes, and pray what is wrong?' a large variety of answers is possible. A man may sophisticate his conscience, or bribe his conscience, or throttle his conscience, or sear his conscience. And so the man who is worst, who, therefore, ought to be most chastised by his conscience, has most immunity from it, and where, if it is to be of use, it ought to be most powerful, there it is weakest.
What then? Why this, then--a standard that varies is not a standard; we are left with a leaden rule. My conscience, your conscience, is like the standard measures which we at present possess, which by their very names --foot, handbreadth, nail, and the like, tell us that they were originally but the length of one man's limb. And so your measure of right and wrong, and another man's measure, though they may substantially correspond, yet differ according to your differences of education, character, and a thousand other things. So that the individual man's standard needs to be rectified. You have to send all the weights and measures up to the Tower now and then, to get them stamped and certified. And, as I believe, this fluctuation of our moral judgments shows the need for a fixed pattern and firm unchangeable standard, external to our mutable selves. A light on deck which pitches with the pitching ship is no guide. It must flash from a white pillar founded on a rock and immovable amid the restless waves. Our need of such a standard raises a strong presumption that a good God will give us what we need, if He can. Such a standard He has given, as I believe, in the revelation of Himself which lies in this book, and culminates in the life and character of Jesus Christ our Lord. There, and by that, we can set our watches. There we can read the law of morality, and by our deflections from it we can measure the amount of our guilt.
But beyond that, the remarks which I have already made in the former part of my sermon may suggest to us, along with this utterance of the prophet's, that one indispensable characteristic and certain criterion of a true message and gospel from God is that it pierces the conscience and kindles the sense of sin. My dear brethren, there is a great deal of so-called Christian teaching, both from pulpits and books in this day, which, to my mind, is altogether defective by reason of its underestimate of the cardinal fact of sin, and its consequent failure to represent the fundamental characteristic of the gospel as being deliverance and redemption. I am quite sure that the root of nine-tenths of all the heresies that have ever afflicted the Christian Church, and of the weakness of so much popular Christianity, is none other than this failure adequately to recognize the universality and the gravity of the fact of transgression. If a word comes to you, calls itself God's message, and does not start with man's sin, nor put in the forefront of its utterances the way by which the dominion of that sin in your own heart can be broken, and the penalties of that sin in your present and future life can be swept away, it is condemned, ipso facto, as not a gospel from God, or fit for man. O my brother! it sounds harsh; but it is the truest kindness, when Nathan stands before the king, and with his flashing eye and stern, calm voice says,' Thou art the man.' Was not that nobler, truer, tenderer, worthier of God, than if he had smoothed David down with soft speeches that would not have roused his conscience? Is it not the truest benevolence that keeps the surgeon's hand steady whilst his heart is touched by the pain that he inflicts, as he thrusts his gleaming instrument of tender cruelty into the poisonous sore? And are not God's mercy and love manifest for us in this, that He begins all His work on us with the grave, solemn indictment of each soul by itself, Thou art the man'?
He showed me all the mercy,
