Avraham sent Eliezer to fetch Rivkah at the earliest opportunity, as soon as she had reached marriageable age.
Eliezer's miracle - where his journey was miraculously shortened, allowing him to complete a 17 day journey in one day - thus spared Rivkah from spending an additional 17 days in an atmosphere of idol worship.
From this we can be assured of the speed with which G-d will send Moshiach, saving the Jewish people from even an additional moment in Exile.
