The fact that the apostles have an official position can easily lead to pride and competition. We see this as James and John seek the top ranks in the kingdom: “Grant us to sit, one at Your right hand and one at Your left, in Your glory” (Mark 10:37). Jesus takes the opportunity to explain the nature of kingdom leadership. God measures greatness, not by position, but by humble service—the true greatness that is open to anyone in any role.
You know that those who are considered rulers of the Gentiles lord it over them, and their great ones exercise authority over them. But it shall not be so among you. But whoever would be great among you must be your servant, and whoever would be first among you must be slave of all. For even the Son of Man came not to be served but to serve, and to give His life as a ransom for many (Mark 10:42-45).
For corrupt people, higher rank means greater power. They wield that power to crush others and enrich themselves. Jesus, who has the highest rank and power, uses it for service and salvation. He trains His disciples to have the same selfless attitude (Philippians 2:1-5). In this view, when Jesus selects men to be apostles, that has nothing to do with male pride or dominance. (They do not choose themselves.) By His design, all roles—including leadership roles—benefit others. They help God’s team to function constructively rather than competitively.
