"...And defenseless. They have no fangs or claws. They can't bite you or outrun you..."(although I have seen them out jump Claude!!!)
"...What's more, sheep are dirty. A cat can clean itself. So can a dog. We even see birds in birdbaths or a bear in a river. But sheep? They get dirty and stay that way."
These are some excerpts from Traveling Light by Max Lucado.
At first, you read these and think, I'm kinda offended by the fact that I'm being compared to a dumb, defenseless, dirty sheep! But, in reality, we ARE like sheep! When it comes to truly knowing what is best for myself, I don't. When it comes to really fighting the spiritual war (and winning) I can't. When it comes to washing away my own sin and being made perfect, IMPOSSIBLE!
I think David, being a shepherd, understood all too well just how much we are like sheep. We need our shepherd. We would not survive without Him.
