Here is a video of a cute little penguin who doesn't want to get in the water. It's funny, because I think sometimes I'm just like that little penguin.
It's so scary sometimes to jump off into the "unknown." I want to, but until you do it, it's just plain SCARY! You go and scope it out, only to think, "Nope, I'm not jumping in that water!" You walk around shaking your head because you see your friends swimming around down there. Surely, it's not so bad. You go back out there, and get right on the edge only to find that you STILL don't have the courage to take the plunge. And then when you least expect it... God gives you the little nudge you need.
Once you have fallen in, you find out that you can swim and that it wasn't that scary after all :-)
