Even man's tendency or desire to conceptualize and worship God cannot be a genetic characteristic if you put any stock in the lesson of history. Religious wars are at least as common as territorial conflicts and once again tend to eliminate the gene pools of those who participate in them. If man is perceived as having a dimension which is independent of his genes, then man can be more adequately defined. If this is what defines mankind, then every human being is of intrinsic inherent worth. Race, age, religion, economics, education, sex, politics, language, and social castes are of no consequence.
All humans have equal worth and dignity.
The definition of mankind that we have arrived at in this discussion is the very definition that the Bible gives. To be created in God's image means to have a makeup which we call a soul that is not genetic in nature, but spiritual in nature. We are not gene-driven robots. We are special beings uniquely created in the image of God with a spiritual makeup that gives us intrinsic, inherent worth.
