Whether we like it or not, the way we answer the tough questions in life shapes how we live-and, ultimately, whether we succeed or fail, live in peace or discontentment, finish life well or finish life with some unfinished business. There are questions that bubble up from our hearts: why does the universe exist, where does evil come from, and is God real? And there are questions that our culture presents us: is cloning ethical, does modern science disprove Christianity and more.
