We all know that anything once done becomes easier to do again. That is true about both good and bad actions, but ill weeds grow apace,' and it is infinitely easier to form a bad habit than a good one. The young shoot is green and flexible at first, but it soon becomes woody and grows high and strikes deep. We can all verify the statement of our text by recalling the tremors of conscience, the self-disgust, the dread of discovery which accompanied the first commission of some evil deed, and the silence of undisturbed, almost unconscious facility, that accompanied later repetitions of it. Sins of sense and animal passion afford the most conspicuous instances of this, but it is by no means confined to these. We have but to look steadily at our own lives to be aware of the working of this solemn law in them, however clear we may be of the grosser forms of evil deeds. For us all it is true that custom presses on us with a weight, heavy as frost and deep almost as life,' and that it is as hard for the Ethiopian to change his skin or the leopard his spots as for those who are accustomed to do evil' to do good.'
But experience teaches not only that evil deeds quickly consolidate into evil habits, but that as the habit grips us faster, the poor pleasure for the sake of which the acts are done diminishes. The zest which partially concealed the bitter taste of the once eagerly swallowed morsel is all but gone, but the morsel is still sought and swallowed. Impulses wax as motives wane, the victim is like an ox tempted on the road to the slaughter-house at first by succulent fodder held before it, and at last driven into it by pricking goads and heavy blows. Many a man is so completely wrapped in the net which his own evil deeds have made for him, that he commits the sin once more, not because he finds any pleasure in it, but for no better reason than that he has already committed it often, and the habit is his master.
There are many forms of evil which compel us to repeat them for other reasons than the force of habit. For instance, a fraudulent book-keeper has to go on making false entries in his employer's books in order to hide his peculations. Whoever steps on to the steeply sloping road to which self-pleasing invites us, soon finds that he is on an inclined plane well greased, and that compulsion is on him to go on, though he may recoil from the descent, and be shudderingly aware of what the end must be. Let no man say, I will do this doubtful thing once only, and never again.' Sin is like an octopus, and if the loathly thing gets the tip of one slender filament round a man, it will envelop him altogether and drag him down to the cruel beak.
Let us then remember how swiftly deeds become habits, and how the fetters, which were silken at first, rapidly are exchanged for iron chains, and how the craving increases as fast as the pleasure from gratifying it diminishes. Let us remember that there are many kinds of evil which seem to force their own repetition, in order to escape their consequences and to hide the sin. Let us remember that no man can venture to say, This once only will I do this thing.' Let us remember that acts become habits with dreadful swiftness, and let us beware that we do not forge chains of darkness for ourselves out of our own godless deeds.
