We feel the need to squeeze humor out of life, so we don't feel so hopeless. That way when really scary things are staring us in the face, we can stand tall and pretend like we're brave. Like Simba in the Lion King, "I laugh in the face of danger: Ahahaha!"
Putting your trust in the Big Man Upstairs really shouldn't be that hard, when you think about it. I mean, who knows better than He does?
So why is it so difficult for me right now?
