Jesus fills our emptiness.
The boat was empty; something was missing. They set out; but they set out without Jesus. They came back empty-handed. Sometimes God allows our best-laid plans to come crashing down around us. He doesn’t do this to torment us, but to teach us to trust in him. Their embarrassment and frustration must have been pretty overwhelming. And then, to make matters worse, Jesus shows up on the shore and asks if they’ve caught anything. And you can imagine the way they growled in response “no, we haven’t caught anything.” And they must have been thinking to themselves, “and mind your own business.” But the apostles needed to recognize their own weakness. They needed to vocalize their own inability to do anything without Jesus. And when they do that, he acts.
