A few years ago, a question was posed to me online: where would you be without God? There are two answers, actually. One is personal, which I'll cover next week. The other is philosophical, a combination of ontological and cosmological arguments going back a thousand years. "God's existence is necessary for my existence" is, in some ways, a faith-based equivalent for "I think; therefore, I am." A very old and original Christian answer to this question is that without God, there would be no "me" to ask the question, much less attempt an answer.
