A Lesson in Greatness: When the disciples begin to debate who will be their leader when Jesus is gone, Jesus tells them that it won't be any of them, unless they change. He reminds them that you can't access God's Kingdom without this change. He is still calling for the same change in us. Kingdom power is only wielded by those with a Kingdom mindset. We will be reminded of that again today, as we listen to Jesus lesson in greatness.
