The Bible states that humans were made in the Imago Dei or image of God. God says in Genesis 1:26–27 that
Let us make man in our image, after our likeness.
This idea is repeated in the New Testament in 1 Corinthians 11:7 and James 3:9.
God has many faces or personalities. In the Old Testament or Hebrew Bible, hundreds of words describe God, and we are offered images of a God who both gets angry at and yet loves his creations, a God who revels in creativity and variation. Further, in the concept of the Christian trinity God has three faces or personalities: creator, perfected human being, and spirit.
All of this aligns with human beings, made in the image of God, as having distinct personalities and having great value as individuals. In contrast to totalitarian doctrines, where humans are a faceless mass, or utilitarian doctrines, where humans are regarded as useful objects or things, in the Biblical worldview, every human is a distinct personality, and every human is infinitely precious, whether he or she has perceived "use value" or not. This has led to the protection of vulnerable human groups, such as disabled children, the mentally handicapped, or the very elderly, who totalitarian dictators like Hitler wanted to exterminate as "useless eaters."
