Childlike Faith: Fearless

They didn't have playground things like this when I was a kid. We had to try and kill ourselves on things like merry-go-rounds and seesaws. This only shows you a small part of what my daughter was climbing on a few weeks ago. I called it the Gladiator training thing. It's a really technical term, right? Basically, the kids climbed up and then had to make their way across to the other side by going from red part to red part. The red steps were suspended on the yellow bars, but could swing back and forth as far as those chains on the bottom allowed them to. My daughter's friend decided to try it out, but then couldn't figure out how to move from one step to the next without my helping her hold the piece still. I looked back, expecting to see my own child needing as much assistance. Instead, she had climbed across over halfway by herself, and was monkeying the rest of the way with confidence.
On other parts of the playscape, she saw various ways of climbing up to the top, studied them for a moment, and then scrambled up. My heart about stopped as I watched her have to almost leap from the top of some of the ladders to the actual "floor." She didn't even notice. Just threw herself down a slide and picked another way to go back up.
So, where do we as humans go from being completely fearless to having heart-stopping fear watching someone else do something? I know some day my daughter will pause and rethink whether or not she should make that jump. But for now, she's more focused on learning to do monkey-bars before she's five (in November). I used to hang upside down from the monkey bars myself when I was younger.
I'm not saying I should just throw myself around and risk getting hurt. But I am saying that in the bigger things, sometimes I hesitate instead of doing what I know I can do. And that's just it. My daughter knows that if she steps across that gap, no matter how high in the air, her legs are long enough to reach and she can safely get where she's going. And deep down inside, I know that I have the knowledge and skills I need to show other people God through my life, my actions, my words. But I still hesitate. I need to quit letting that fear control me. Fear isn't from God. It's from the devil.
And I need to be more like my daughter: fearless.
Do you hesitate before you leap? What's holding you back from doing what, deep down inside, you know you can?
