  Other arguments against DDI appeal to Scripture's depiction of God as changing, e.g., in the Flood story. Facing such texts, DDI's friends defuse the appearance of divine change by appeal to doctrines less speculative and theoretical than DDI. Thus Philo argues from God's foreknowledge of the future and constancy of character that God cannot repent or feel regret, as the Flood story suggests. The Incarnation is an especially knotty problem for DDI's Christian friends. In general, these argue that all change it involved occurred in the human nature God the Son assumed rather than in God; God was eternally ready to be incarnate, and eternally had those experiences of the earthly Christ which the Incarnation makes part of his life. Through changes in Mary and the infant she bore, what was eternally in God eventually took place on earth.
