Just as God saw Nineveh as a great city to be infiltrated by God's people, he also looks upon our great cities that need to be infiltrated by God's people. However, just because we know what God desires doesn't always mean we desire the same thing. Jonah was so against the will of the Father, that he risked his life and paid the fare to sail to the other side of the world so Gods creation wouldn't hear about grace. In contrast, Jesus was so committed to the will of the Father that he gave his life and paid the ultimate fare so a world that would not accept Him would be extended saving grace.
