Eastern religion sees the most holy people as those who withdraw from the world, treat their bodies harshly, and deny themselves the normal pleasures of life. Genesis, by contrast, teaches us that the created world is good and pleasing to God. God made the earth as the perfect environment for the creatures he then put in it, and he got a kick out of it. He was pleased with what he had done. So God created man in his own image.
Human life is sacred.
That is why for the Christian, as for the Jew and Muslim, who also believe this, abortion on demand and euthanasia are abhorrent. All human life, from womb to grave, is sanctified by this truth, that humans are created in the image of God as the apple of his eye. Human life belongs to him and has the purpose of glorifying him. This sanctity of human life is the basis for the Jewish and Christian doctrine of the equality of all humans in the sight of God. Unlike for example the Hindu caste system, where human life has more or less value according to your rank in society.
