Christians are often asked to defend God, from attacks using the problem of evil: If God is good, and all-powerful, why are there things such as earthquakes, meteors, and Alzheimer's? Why does God allow human-caused evils, like global climate change, child sexual exploitation, and war? These can be serious questions, and hard ones to answer. This area of thought is often called "the problem of evil." C. S. Lewis answered that problem in his The Problem of Pain.
There are, then, problems for Christians. However, there are corresponding problems, much less frequently discussed, for atheists, namely the problem of good. As N. T. Wright put it in his Surprised by Scripture: Engaging Contemporary Issues, if the universe is here because of mindless chance, how is it that there is so much in our surroundings to appreciate and cherish: leaf colors, rainbows, music, innocent laughter, beautiful human constructions, unselfish good deeds, uplifting literature, and much more?
