Being prepared is a noble trait. We respect those who are prepared and we strive to be prepared ourselves. However, sometimes we limit ourselves and what we can do by feeling as if we need to be more prepared before starting a task. NIKE made a lot of money by telling the world to "Just Do It". Not only do we just need to do it, but we also need to realize that when it comes to God's work, we aren't doing "it" at all. He is doing all of it through us.
Lord, thank you that I don't actually need to do anything other than make myself available for You to do Your work through me.
