A King was having some guest in His mansion, and He had so many vessels of gold, slivers, diamond, wood, clay etc. Being a benevolent man, everyone had access to the vessels he had. When it was time to make a toast, He ordered His savants to get Him a drink, but on getting there they found out that all the special vessels where occupied and they came trembling to the King saying "there are no more vessels of gold, sliver or diamond" then the king asked which is AVAILABLE, and they to Him "The Clay vessel" the King said get it, and they brought it before the King. Everyone marvelled to see the King drinking from a clay vessel, and somehow everyone preferred the clay vessel because that's what the King was using. Your relevance is because you are available for God's use.
