Their argument over greatness is full of irony in its setting, given that, on the road Jesus is telling them how his greatness as the messiah with play out in his sacrifice. Jesus is defining greatness for them and they are unable to hear it and unwilling to get clarification. Instead of asking Jesus what he means, they turn to each other and, using their own criteria of greatness, begin to exalt themselves and belittle each other in order to claim their own greatness. Its not the only time they argue about this. Like others both now and throughout history who have been attached to those they see rising to power, Jesus disciples are looking for their own benefit from his power. They argue about who among them is greatest, who gets what seat in Jesus throne room. And you know how these discussions go, right? As these individuals jockey for position among each other, they highlight their own successes and talents and ignore their own weaknesses, while highlighting each others weaknesses and ignoring others strengths. So after their roadtrip through Galilee they arrive in Capernaum at their destination, and Jesus puts them on the spot- sort of like when you ask your kid how their day at school was, but you already got the text from their teacher telling you exactly how their day was. And just like that busted child, the disciples silently sit in the back seat hoping you just move on or the phone rings- anything to change the conversation. And once again, Jesus is reminded that they don’t get it- yet another frustration due to their lack of comprehension of Jesus mission, one of many throughout the gospel of Mark. And so Jesus takes the moment to try again to help them understand the upside-down nature of his purpose and mission. So he calls them together to make a point about the importance of servanthood , not power, as what truly defines greatness, right? You want to be great in this kingdom? You want to be closest to me, closest to the throne of my kingdom? Well then, forget that “i’m better than you” stuff and serve those around you unfailingly.
