"Noach opened the window of the ark... Even while it is still the time of exile a state of flooding prior to the redemption a Jew might conclude that perhaps the end of the flood has come. At this point, he must leave the ark and head out into a "new world," a Redemption world. He must do all he can to clarify the matter, including sending out messengers.
A Jew must not sit by idly and wait until G-d commands him to leave exile and enter the Redemption. He must do everything he can to hasten the Redemption. Although leaving the exile and entering the Redemption can only be according to G-d's directive, nevertheless, when G-d sees Jews yearning for the redemption to come immediately, this itself quickens the commandment to be issued forth from G-d to "leave the ark," to leave the exile for the Redemption.
(The Lubavitcher Rebbe, 10 Tammuz 5745)
