We all know that, whether we regard it as we ought or no. We all say Amen to that, when it is forced upon our attention. There _is_ something in us that thwarts aspiration towards good, and inclines to evil.
'What will but felt the fleshly screen?'
And it is not only a screen. It not only prevents us from rising as high as we would, but it sinks us so low as to do deeds that something within us recoils from and brands as evil. Jesus teaches us that he who commits sin is the slave of sin; that is to say, that an alien power has captured and is coercing the wrongdoer. That teaching does not destroy responsibility, but it kindles hope. A foreign foe, who has invaded the land, may be driven out of the land, and all his prisoners set free, if a stronger than he comes against him. Christianity is called gloomy and stern, because it preaches the corruption of man's heart. Is it not a gospel to draw a distinction between the evil that a man does, and the self that a man may be? Is it not better, more hopeful, more of a true evangel, to say to a man, 'Sin dwelleth in you,' than to say, 'What is called sin is only the necessary action of human nature'? To believe that their present condition is not slavery makes men hopeless of ever gaining freedom, and the true gospel of the emancipation of humanity rests on the Christian doctrine of the bondage of sin.
Let me remind you that freedom consists not in the absence of external constraints, but in the animal in us being governed by the will, for when the flesh is free the man is a slave. And it means that the will should be governed by the conscience; and it means that the conscience should be governed by God. These are the stages. Men are built in three stories, so to speak. Down at the bottom, and to be kept there, are inclinations, passions, lust, desires, all which are but blind aimings after their appropriate satisfaction, without any question as to whether the satisfaction is right or wrong; and above that a dominant will which is meant to control, and above that a conscience. That is the pyramid; and as by the sunshine on the gilded top of some spire, the shining apex, the conscience, is illnmined when the light of God falls upon it. And when a man is built in that fashion, and keeps to that fashion, then, and only then, is he free.
I need not remind you of how the metaphor of my text receives its most tragical and yet most common illustration and confirmation in the awful fact of the power of any evil thing, once thought or done by a man, to reproduce itself, onwards and ever onwards. It is a far commoner thing for a man never to have done some given evil, never to have got drunk, never to have stolen, or the like, than to have done it only once. I have heard of a mysterious illness, in which at first medical analysis detected with difficulty one single bacterion in a great quantity of blood. But in a few days, so had they multiplied that no drop could be taken anywhere from the veins which was not full of them. That is how men get under the slavery of any evil thing; and habit becomes stronger than anything except that "strong Son of God, immortal Love," whose Spirit can conquer even it." Can the Ethiopian change his skin, or the leopard his spots? Then may ye that are wont to do evil learn to do well." The bondage is real and hard.
My text suggests to us that strange, sad fact
