Not of this world

On John 18:36: 

His kingdom (yes, he agrees he has a kingdom; Pilate seizes on this) doesn't come from this world. Please note, he doesn't say, as some translations have put it, ' my kingdom is not of this world'; that would imply that his 'kingdom' was altogether other-worldly, a spiritual or heavenly reality that had nothing to do with the present world at all. That is not the point. Jesus, after all, taught his disciples to pray that God's kingdom would come 'on earth as in heaven'. 

No: the point is that Jesus' kingdom does not come from 'this world'. Of course it doesn't. 'The world', as we've seen again and again, is in John the source of evil and rebellion against God. Jesus is denying that his kingdom has a this-worldy origin or quality. That's why he has come into the world himself (v37), and why he has sent, and will send, his followers into the world (17.18; 20.21). His kingdom doesn't come from this world, but it is for this world. That is the crucial distinction.  (John for Everyone, Tom Wright, p114-115)
