Jesus doesn't rebuke His disciples for wanting to be great; instead He gives them a roadmap for how to achieve greatness. The recipe for greatness in God’s kingdom: Find someone to serve and don’t worry about getting any credit for it.  To transcend one's own desires and willingly suffer for the sake of others is the example of our Lord and the path to true greatness. Mk. Phil. 1 Cor Ro. Eph. 1 Cor. Col. Jn. 13
