“Throughout the Old Testament, mankind’s sinfulness is set in contrast with the holiness and righteousness of God. In addition, here we begin to trace such great overarching theological themes as election-love, the covenant, and the kingdom of God. It is to the Old Testament that we look for the moral law of the Ten Commandments and the social and ethical teachings of the prophets. It is here that we also turn for our biblical background for understanding the claims of Jesus concerning his messiahship, priesthood, and atonement.” Marvin R Wilson, Our Father Abraham
