I absolutely love this quote attributed to Martin Buber at C. Orthodoxy.
What is the difference between Jews and Christians? We all await the Messiah. You believe He has already come and gone, while we do not. I therefore propose that we await Him together. And when He appears, we can ask Him: “Were you here before?”… And I hope that at that moment I will be close enough to whisper in his ear, “For the love of heaven, don’t answer.”
