“And hearing this, the ten became indignant with the two brothers” (Matthew 20:24).
Don’t think the ten so noble that theirs is a righteous indignation. They have revealed enough of their own self-serving attitudes, in other contexts, to suppose that the outrage is more about having been “beat to the punch.” Their jealous greed has been exposed; that James and John might obtain something they, themselves, desired. I hope you are not disappointed. Where people are involved, conflict is inevitable. If the twelve disciples could not get along perfectly, even while Jesus was in their very midst, it certainly offers us reassurance as his imperfect church. That the church has survived and performed its missional task for 2000 years, despite disciples like us, bears continuing affirmation of its divine origin.
