ויהי ידיו אמונה - עד בא השמש

When the Jews were fighting Amalek at the end of Beshalach the pasuk says about Moshe "Vayihe yadav emunah" - Literally "His hands were emunah". The Targum translates that Moshe's hands were spread out in prayer. The Besht Hakadosh explains that Moshe was davening to Hashem for emunah!

May I add that the pasuk concludes "ad bo hashemsh" - until the sun comes. If we daven for emunah we can be assured that it will eventually shines its healing rays of light upon us.

Beloved friends! We must constantly pray for emunah, that we should wholeheartedly believe that AIN OD MILVADO - nothing else truly exists or matters but Hashem.
