With reference to relevant examples, explain what Christians understand by the principle of the Sacredness of Human Life. 
Beliefs about the sanctity of life lie at the heart of all the ethical debates on embryo experiments, abortion and euthanasia. This is the Christian belief that all life is a sacred gift from God, and that humans are not at liberty to destroy or experiment with it. All humans are created ‘Imago Dei’ – in the image of God – and have intrinsic worth. In examining why they believe this, a good place to start is what the Bible says.
According to the Christian Institute, the Bible clearly supports the view that life begins at conception. The fundamental prohibition on killing, and the basis for it, is set out in Genesis 9:6: “Whoever sheds the blood of man, by man shall his blood be shed; for in the image of God has God made man.” Only man has a soul. Only man was made in God’s image, God’s likeness (Genesis 1:26). The Bible talks of God knowing an individual from conception (Jeremiah 1:5). David said he was “sinful from the time my mother conceived me”. So David was in need of a Saviour from the very point of his conception.
