Gospel of Mark - Ambition for Greatness or a Quest for the Kingdom

Mark 9:33-50 covers the disciples' argument about who is the greatest, Jesus' teaching that greatness in His kingdom comes through humility and service, the importance of accepting and not hindering those who are not with the inner circle but are doing good in His name, and a severe warning about the dire consequences of leading "little ones" (believers) into sin, emphasizing self-sacrifice to avoid greater judgment.
