Distance For Closeness

In our sources, the Jewish people are compared to a Niddah when banished by Hashem for our sins. This is an interesting metaphor. Chazal say that the distance a Niddah must keep from her husband is in order that when they get back together it should be exciting. That means that the entire purpose of the hester ponim and tribulations that we suffer is in order to make it so much more exciting when we get back together.
