G.K Chesterton

If Christianity should happen to be true -- that is to say, if its God is the real God of the universe -- then defending it may mean talking about anything and everything. Things can be irrelevant to the proposition that Christianity is false, but nothing can be irrelevant to the proposition that Christianity is true. [All] things not only may have something to do with the Christian God, but must have something to do with Him if He lives and reigns.
