In Matthew 18, Jesus's disciples asked him who is the greatest in the kingdom of heaven. Jesus's answer is unexpected because he doesn't name any of them. Instead, between chapters 18 and 19 he answers their question through a series of difficult statements and parables intended to shape their view of what greatness truly looks like in the kingdom of heaven. While none of them were the greatest, what did Jesus tell them it would take for them to be simply great disciples?
