Faith on earth?

After the story of the widow and the judge come a promise and a question. God will see justice done quickly. But will the Son of Man find faith when he comes? The Greek says: the faith. Many interpreters think of that widow's faith, the faith that kept knocking.

It is a question without an answer, and that is probably the point. Quickly, and yet a long wait: he doesn't resolve that tension. He doesn't ask whether people know the right things. He asks whether they keep asking when the answer is slow to come.
