Mat 11:22 But I tell you, It shall be more tolerable for Tyre and Sidon at the day of judgment, than for you.

"Day of judgment" is hêmera (day) krisis (a separating, the power of distinguishing, a decision).

When Christ discusses the judgment, he is always talking about separating one group of people from another. Of course, our personal day of judgment is also a separation: our separation from our lives.
