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.
II. Our evil deeds imprison us for good.
The tragedy of human life is that we weave for ourselves manacles that fetter us from following and securing the one good for which we are made. Our evil past holds us in a firm grip. The cords which confine our limbs are of our own spinning. What but ourselves is the reason why so many of us do not yield to God's merciful drawings of us to Himself? We have riveted the chains and twined the net that holds us captive, by our own acts. It is we ourselves who have paralysed our wills, so that we see the light of God but as a faint gleam far away, and dare not move to follow the gleam. It is we who have smothered or silenced our conscience and perverted our tastes, and done violence to all in us that 'thirsteth for God, even the living God.' Alas! how many of us have let some strong evil habit gain such a grip of us that it has overborne our higher impulses, and silenced the voice within us that cries out for the living God! We are kept back from Him by our worse selves, and whoever lets that which is lowest in him keep him from following after God, who is his 'being's end and aim,' is caught and prisoned by the cords woven and knitted out of his sins. Are there none of us who know, when they are honest with themselves, that they would have been true Christians long since, had it not been for one darling evil that they cannot make up their minds to cast off? Wills disabled from strongly willing the good, consciences silenced as when the tongue is taken out of a bell-buoy on a shoal, tastes perverted and set seeking amid the transitory treasures of earth for what God only can give them, these are the 'cords' out of which are knotted the nets that hold so many of us captive, and hinder our feet from following after God, even the living God, in following and possessing whom is the only liberty of soul, the one real joy of life.
