Bear with me on this one. I know the title is weird.
2 Corinthians 4:7 says, "But we have this treasure in jars of clay, to show that the surpassing power belongs to God and not to us." Okay, let's look at the context. The treasure referenced here is the "light of the knowledge of the glory of God" (v6) The knowledge. I find that fascinating.
I can just see the clay pot, light spilling out of its many cracks. It's fantastic imagery. One day I was sitting thinking about this and I realized that light and knowledge and joy doesn't just shine through those cracks - it spills out of them and pretty soon it needs to be refilled.
We are leaky.
Think of how true this is. We hear a sermon; it fills us up with knowledge. The next week, it's all but forgotten. We experience the Lord's intervening firsthand. We are filled with amazement. The next week, it's spilled out the cracks and no longer a reality to us. We are at a Bible Study and the text fills us with the joy of the Lord. But it doesn't stay - it can't. We are leaky.
Our cracks will not be sealed until the next life. While we are still in these shadow lands, we must be continually refilled with the light of the knowledge of God's Glory. Over and over again. This is why weekly Bible studies are so important. Daily reading and praying. Regular fellowship with the body. We must immerse ourselves in the Truth.
We've all come to those places where we are absolutely empty. There's nothing left, there's no motivation, no joy. Fill up with Him. Sometimes we can't do it ourselves. Sometime God will fill us with the words of friend or stranger.
So don't be discouraged when you realize you've been leaking out the glory. It's inevitable. It's what keeps us coming back to our knees.
