In this study, Josh teaches through Mark 9:30–41, revealing how Jesus defines true greatness in the kingdom of God. As Jesus foretells His death, teaches His disciples to be servants, welcomes a little child, and corrects John’s pride, He turns the world’s definition of greatness upside down. True greatness is not found in power, influence, or recognition, but in love, sacrifice, humility, and service. This message challenges believers to put others before themselves, serve faithfully, and make Christ the greatest of all.
