Epiphany is the revealing of God as the God for the World. The wise men from the East remind us that Jesus hasn't jus come for the Jews or that God's grace isn't localized to one place and to one people. Even so, though God's grace may be for the world, few have the eyes, ears and hearts, to see it, hear it and receive it. So, Jesus here in Luke 18 tells us, "The Kingdom of God is coming in ways that cannot be observed." The Kingdom of God was in their midst as Jesus and yet, as he goes on, he explains that he was rejected. The very thing that was longed for in Jesus is rejected when he came among them in ways that they didn't expect.
