Christianity is realistic because it says that if there is no truth, there is also no hope; and there can be no truth if there is no adequate base. It is prepared to face the consequences of being proved false and say with Paul: If you find the body of Christ, the discussion is finished, let us eat and drink for tomorrow we die. It leaves absolutely no room for a romantic answer.

As my son Frankie put it, Humanism has changed the Twenty-third Psalm: They began - I am my shepherd. Then - Sheep are my shepherd. Then - Everything is my shepherd. Finally - Nothing is my shepherd.

In face of this modern nihilism, Christians are often lacking in courage. We tend to give the impression that we will hold on to the outward forms whatever happens, even if God really is not there. But the opposite ought to be true of us, so that people can see that we demand the truth of what is there and that we are not dealing merely with platitudes. In other words, it should be understood that we take this question of truth and personality so seriously that if God were not there we would be among the first of those who had the courage to step out of the queue.

Christian art is the expression of the whole life of the whole person as a Christian. What a Christian portrays in his art is the totality of life. Art is not to be solely a vehicle for some sort of self-conscious evangelism.

The command is to love him, not just to think about him, or do things for him. We are not to stop with a proper legal relationship - for example, to think of a man as legally lost, which he is, in the sight of a holy God - without thinking of him as a person. Saying this, we can suddenly see that much evangelism is not only sub-Christian, but subhuman - legalistic and impersonal.

But the dignity of human life is unbreakably linked to the existence of the personal-infinite God. It is because there is a personal-infinite God who has made men and women in His own image that they have a unique dignity of life as human beings. Human life then is filled with dignity, and the state and humanistically oriented law have no right and no authority to take human life arbitrarily in the way it is being taken.

I have come to the conclusion that none of us in our generation feels as guilty about sin as we should or as our forefathers did.
