At the marriage at Cana, they ran out of wine. Jesus took empty vessels, had them filled with water, and He turned that water to wine. Think what He can do with us if we will just empty ourselves of all the anger, envy, lust, materialism, anxiety, worry, doubt, etc. He calls us to be empty vessels so that we can be filled with His Holy Spirit and be more like Him. Our prayer should be "Create in me a clean heart oh God, and flow more greatly through my heart so that I may be more like You".
