Willing Vessel

Pastor Wyatt Simmerman preached on being a willing vessel today.
We talked about a few different stories today. David and Moses were the two main ones. They each had something in their hands that they used. Moses had a rod and David had a sling. It was not the object that was used, but rather the willing vessel that they made themselves.
So we ask you these questions.
Have you proved your weapons? What's in your hand? And are you willing to use it for God's Kingdom?
