Chazal (Shabbos 31.) say, זרעים סדר זה אמונת, emunah is the tractate of seeds.
A seed sprouts forth salvations, as we say in Shacharis, ישועות מצמיח, that Hashem sprouts forth salvations. מצמיח generally refers to when something sprouts from a seed. The salvations grow from the seed of emunah.
Before birchas hachodesh, people want to know when the molad will be. Some prepare themselves before Shacharis. They ask, "When is the molad this month?" Some check the calendar. Indeed, the siddur states, נכון החודש שמברכין קודם המולד לידע , "It is proper for one to know when the molad is before he says birkas hachodesh."
It is לידע נכון, "proper to know,' but when it comes to knowing Hashem, it is an obligation from the Torah, as it states (Devarim 4:39) האלקים הוא 'ה כי לבבך אל והשבת היום וידעת, "You shall know this day and take to your heart that Hashem, He is the G-d." We are obligated to know and review the Emunah. It isn't sufficient to know it in our subconscious. It needs constant reminders and reviews. And with this emunah, we will merit salvations.
