These secret faults are like a fungus that has grown in a wine-cask, whose presence nobody suspected. It sucks up all the generous liquor to feed its own filthiness, and when the staves are broken, there is no wine left, nothing but the foul growth. Many a Christian man and woman has the whole Christian life arrested, and all but annihilated, by the unsuspected influence of a secret sin. I do not believe it would be exaggeration to say that, for one man who has made shipwreck of his faith and lost his peace by reason of some gross transgression, there are twenty who have fallen into the same condition by reason of the multitude of small ones. 'He that despiseth little things shall fall by little and little'; and whilst the deeds which the Ten Commandments rebuke are damning to a Christian character, still more perilous, because unseen, and permitted to grow without check or restraint, are these unconscious sins. 'Happy is he that condemneth not himself in that thing which he alloweth.' III. Notice the discipline, or practical issues, to which such considerations should lead. To begin with, they ought to take down our self-complacency, if we have any, and to make us feel that, after all, our characters are very poor things. If men praise us, let us try to remember what it will be good for us to remember, too, when we are tempted to praise ourselves--the underworld of darkness which each of us carries about within us. Further, let me press upon you two practical points. This whole set of contemplations should make us practise a very rigid and close self-inspection. There will always be much that will escape our observation--we shall gradually grow to know more and more of it--but there can be no excuse for that which I fear is a terribly common characteristic of the professing Christianity of this day--the all but entire absence of close inspection of one's own character and conduct. I know very well that it is not a wholesome thing for a man to be always poking in his own feelings and emotions. I know also that, in a former generation, there was far too much introspection, instead of looking to Jesus Christ and forgetting self. I do not believe that self-examination, directed to the discovery of reasons for trusting the sincerity of my own faith, is a good thing. But I do believe that, without the practice of careful weighing of ourselves, there will be very little growth in anything that is noble and good.
