One of the most difficult problems in Christian theology is the problem of theodicy: the problem of evil and suffering. The philosopher David Hume summarized the problem; “Is he (God) willing to prevent evil, but not able? then is he impotent. Is he able, but not willing? then is he malevolent. Is he both able and willing? whence then is evil?” Christians believe God is all powerful (omnipotent), all knowing (omniscient), all good (Omnibenevolent), and present everywhere at once (omnipresent). So Hume’s question goes like this; if God is all powerful and there is evil in the world, then God must not be good; however, if God is all good and there is evil in the world, then God must not be all powerful. What God can not be is all powerful and good because there is such a thing as evil. But Christians say that God is all powerful and good; so why is there evil in the world?
Free will or fate? You must decide, but ignore the irony for now. Within Christianity there is an ongoing debate over whether God chooses those He saves or those saved choose to be saved. Those who emphasize God’s choosing trace back to John Calvin and are known as Calvinists. Those who emphasize man’s choosing trace back to Jacob Arminius and are known as Arminians. So who is right, the Calvinists or the Arminians? Does God pick us or do we pick God?
