"But we have this treasure in jars of clay to show that this all-surpassing power is from God and not from us." -- 2 Corinthians 4:7
I find it interesting that whenever I buy a bouquet of flowers for my wife she is focused on the flowers and cares very little for the vase. The poor little guy just sits there unassuming, holding all the beautiful flowers together for everyone to see and appreciate. And that's the way it should be; to show God's beautiful flowers.
Paul tells us that the Lord "made his light shine in our hearts" (vs. 6). We are merely the little vases in which he shines. The world is meant to see the "all-surpassing power" from God in our "vases"... or "jars of clay". It's not about us and all that we can be; it's all about the Lord and all that can be seen of him. And that's the way it should be; to show God's bountiful power.
What do others see when you come around my friend? Are you more concerned that they see the vase that they miss the flowers you contain? Do they ever see the "all-surpassing power" from God in your life and marvel at him? Don't ever forget... we're just "jars of clay". And that's the way we should be: to show God's overwhelming glory.
