When the Rebbe of Aleksander, HY”D, was being led to his death, he explained this Possuk: “L'hagid baboker chasdecha v'emunascha baleilos.” Meforshim explain, he said, when it is ‘morning’ - bright and comfortable - we praise Hashem for His kindness; when it is ‘night’ - dark and painful - we declare our Emuna in Him. The Rebbe asked: in that case shouldn't we say V'emunaseinu Baleilos, being that we refer to our Emuna in Him, not Emunascha, i.e. your (Hashem's) Emuna?
The Rebbe explained: indeed, Emunascha refers to Hashem's Emuna in us! We rejoice when Hashem sends us a ‘night’ - in his case the Nazis YM”Sh - it means He believes in us.
Let's rejoice that Hashem has Emuna in us - He trusts our generation with a Nisayon that He didn't give any previous generation. He knows we can pass this test and will celebrate with us. Hatzlocha, friends. Let’s show Hashem we understand his message.
