Be'haloscha - being prepared

In this weeks parsha we are told
Miriam asked why Moshe was different
then everyone else in the sense that he separated
(then divorced) his wife when everyone else did
not do so. It says Hashem called Aron and Miriam
suddenly - Rashi explains this means right after
 they performed the mitzva of "be fruitful and multiply"
they were looking for a mikva with which to purify themselves
(Hashem decreed that the mitzva makes one impure regardless
of the level of the person until immersion in a mikva)
Specifically at that moment Hashem called for them
before they were (as it were) prepared to speak with Him.
 This explained the difference: Moshe had to be prepared
to speak with G-d 24/7 and therefor had to remain on a higher level of purity
at all times, this was not required of other people.
Some lessons I learn:

Sometimes it seems we are most prepared when we are least prepared
As it says Moshiach will come "be'hesach da'as" - when our concentration is
distracted, meaning when we are least preparing for Moshiach that is the best
time for him to come. Precisely at this time when this world looks so
unprepared for Moshiach (depends which news sites you've been looking at)
this is the time when he is coming.
