Luke says he was constantly in a bruised condition, and that he had an unclean spirit. The young man could scream and shout and cry, but in these rages there was a constant urge to destroy himself.
What is true of the boy is true of us also before we are converted, spiritually. We don't realise how much danger we are in, how constantly sin is getting its tentacles into us. We say, ‘I want my moral liberty; I want to do as I please. I don't want God’s laws restricting me. I don't want holiness.’ So we tell lies and make excuses. We act selfishly, we act proudly, and at the same time are very pleased with ourselves. We boast and misrepresent things in our favour. Yes, and these things are getting worse and worse. ‘They aren’t’ we protest. ‘I can control how I think and what I say.’ No, you can't. In ten years-time you will be much worse than you are today, much more firmly held in the grip of sin. All the small liberties you allow yourself today will become medium-size liberties, and then huge liberties. If your problem is uncleanness, you get to be a thoroughgoing deviant with the passage of time. All these things increase their hold, and that young man is a picture of what happens. You are under the control of the sinful life, the unbelieving life, the life away from God.
Although we are responsible for our sins, yet we are trapped in them. You become a hapless, hopeless victim, because unbelief and godlessness and self-serving, gets hold of you and controls you just like this poor youth. You see it every day on the television and in the news: the moral excesses of our day. All the old rules of society and of humanity and of the Bible have been thrown away. You can do the opposite of everything that used to be regarded as decent and moral, and that is applauded and defended. Everything is turned round. There is no authority in our lives, morally, spiritually. That is the cost and the danger of being away from God. You think of this boy’s anguish and his frustration, and as an unbeliever you will be very frustrated by life.
