What does the Bible say about humility in the kingdom of God?

In Mark 9:33-37, Jesus emphasizes the importance of humility by stating that whoever desires to be first must be last of all and servant of all. He uses a child as a profound example, indicating that one must become like a little child to enter the kingdom of God. This reflects the nature of true greatness in God's economy: not through power or authority, but through humility and service to others. Humility is a hallmark of those who belong to Christ, contrasting sharply with worldly views of greatness.
