At the outset, let us remember that every worldview—not just Christianity’s—must give an explanation or an answer for evil and suffering. Either evil categorically proves that God does not exist, as the atheist avows, or evil is “not ultimately real evil,” as the pantheist claims, or evil is most coherently explained by the Christian view of God and His purpose in creation. In short, this is not a problem distinctive to Christianity. It will not due for the challenger just to raise the question. This problem of evil is one to which we all must offer an answer, regardless of the belief system to which we subscribe.
