You remember the grand vision of Isaiah, how, when he saw the King sitting on His throne, 'high and lifted up, and His train filled the Temple,' the first thought was, not of rapture at the Apocalypse, not of adoration of the greatness, not of aspiration after the purity, not of any desire to join in the 'Holy! Holy! Holy!' of the burning spirits, but 'Woe is me, for I am undone; for mine eyes have seen the King; for I am a man of unclean lips.' Ah, brethren! whenever the commonplaces of our professed religious belief are turned into realities for us, and these things that we have all been familiar with from our childhood, flame before us as true and real, then there comes something analogous to the experience of that other Old Testament character--'I have heard of Thee by the hearing of the ear, but now mine eyes see Thee; wherefore I abhor myself, and repent in dust and ashes.' And then there comes, in like manner, and there ought to come, along with this new vision of a God in His purity, and the new sense of my own sinfulness, the apprehension of personal evil. For, although it be the lowest of its functions, it is a function of conscience, not only to say to me, 'It is wrong to do what is wrong,' but to say, too, 'If you do wrong, you will have to bear the consequences.' I believe that a part of the instinctive voice of conscience is the declaration, not only of a law, but of a Lawgiver, and that part of its message to me is not only that sin is a transgression of the law, but that 'the wages of sin is death.' Now, let me ask you to ask yourselves whether it is not a strange and solemn and sad testimony to the reality and universality of the fact of sin that the sense of impurity and dread of its issues are the uniform results of any vivid, thrilling consciousness of nearness to God. And let me ask you to ask yourself one other question, and that is, whether it is a wise thing to live upon a surface that may be shattered at any moment; whether that is true peace which needs but a touch to melt away; whether you are wise with all this combustible material deep down in your conscience, in paying no regard to it but living and frolicking, and feasting and trafficking, and lusting and sinning on the surface, like those light-hearted, light-headed fools that build their houses on the slopes of volcanoes when the lava rush may come at any moment? II. That brings me to note, secondly, the mistaken cry of fear.
