In the context, Jesus is not using these stories to teach that God is more concerned about unsaved people than saved. He is using them to justify to the Pharisees why he hung out with sinners at all. I'm not arguing the contrary (that God is more concerned about Christians than non-Christians), but simply that evangelism and discipleship are a single, integrated process and cannot be arbitrarily separated.

God may have called City Life to ruthlessly prioritise ministry to unbelievers over believers, but to generalise it to God's call on the Church universal is asking too much of the text.
