Further, the centurion saw himself from the inside, and that makes all the difference. Ah, brethren! most of us know our own characters just as little as we know our own faces, and find it as difficult to form a just estimate of what the hidden man of the heart looks like as we find it impossible to form a just estimate of what we look to other people as we walk down the street. But if we once turned the searchlight upon ourselves, I do not think that any of us would long be able to stand by that plea, 'I am worthy.' Have you ever been on a tour of discovery, like what they go through at the Houses of Parliament on the first day of each session, down into the cellars to see what stores of explosive material, and what villains to fire it, may be lurking there? If you have once seen yourself as you are, and take into account, not only actions but base tendencies, foul, evil thoughts, imagined sins of the flesh, meannesses and basenesses that never have come to the surface, but which you know are bits of you, I do not think that you will have much more to say about 'I am worthy.' The flashing waters of the sea may be all blazing in the sunshine, but if they were drained off, what a frightful sight the mud and the ooze at the bottom would be! Others look at the dancing, glittering surface, but you, if you are a wise man, will go down in the diving-bell sometimes, and for a while stop there at the bottom, and turn a bull's-eye straight upon all the slimy, crawling things that are there, and that would die if they came into the light. 'I am not worthy that Thou shouldest enter under my roof.' But then, as I have said, most of us are strangers to ourselves. The very fact of a course of action which, in other people, we should describe with severe condemnation, being ours, bribes us to indulgence and lenient judgment. Familiarity, too, weakens our sense of the foulness of our own evils. If you have been in the Black Hole all night, you do not know how vitiated the atmosphere is. You have to come out into the fresh air to find out that. We look at the errors of others through a microscope; we look at our own through the wrong end of the telescope; and the one set, when we are in a cynical humour, seem bigger than they are; and the other set always seem smaller. Now, that clear consciousness of my own sinfulness ought to underlie all my religious feelings and thoughts. I believe, for my part, that no man is in a position to apprehend Christianity rightly who has not made the acquaintance of his own bad self. And I trace a very large proportion of the shallow Christianity of this day as well as of the disproportion in which its various truths are set forth, and the rising of crops of erroneous conceptions just to this, that this generation has to a large extent lost--no, do not let me say this generation, _you and I_--have to a large extent lost, that wholesome consciousness of our own unworthiness and sin.
