For many who call themselves Christians, 'Take it on faith' is a mantra they use when they can't explain something. But in fact, faith should be built on evidence.
Annie's claim that “The Sun'll come out Tomorrow,” was a good example of real faith. After all, tomorrow's sun hasn't come out yet. We believe it will come out, we have faith it will come out. It requires faith (albeit very little) to believe it, because it is an event that hasn't happened yet.
But our belief in it is based on evidence: The sun came out today, it came out yesterday, etc.
