Why does Mark select the healing of the demon-possessed man as the first attestation in his Gospel? Peter, the ultimate author of this Gospel, had been at Cana in Galilee; he had seen the turning of water into wine. He may have been among those who knew about the healing of the nobleman’s son, and he knew about other miracles too.
Here is this demonised man saying, ‘Have you come to destroy us demons? You keep to your sphere; we will keep to ours.’ ‘What have we to do with thee?’ We have nothing in common. Isn’t this how some of us think before we are converted? He utters a prayer against God. Go away; in effect, leave me alone. Who is saying that to God? You may happen to be in church, but in your own private life you are praying against any influence of God in your life. What a tragedy that is, dear friends. What an awful thing to push away the Saviour of the world. This is Christ’s world. He made everyone. He owns everyone by rights. We owe him our lives. If we fail to repent and seek him and find him, we will be eternally judged. We have no right to be here as rebels against God. People say, I don’t want to be changed, or become a Christian. I won’t talk deeply with that Christian again. They are trying to get away from any influence of the gospel on them.
It seems that in Bible times demons could occupy human beings, often without any desire on the part of those people; even children were demonised. The demons of darkness could to a considerable extent get into people, Gentiles as well as Jews. It was a terrible thing. In this case it seems that this man was deeply immoral and so abandoned in his life that he exposed himself to possession, but apparently some people were demonised who did not expose themselves to it, and there appears to have been quite a rise in this phenomenon just before the coming of Christ. The reason was that Christ would cast them out, and one of the great blessings and benefits to this fallen world since the time of Christ, is that there has been very little demon possession. What became almost common-place was eradicated. It was a sign. Nowadays there is not the same involuntary demon possession. It appears you can only become demonised, if you sell yourself out to it. Perhaps you would be up to your neck in occult practice.
