Speaking About Hashem’s Wonders Creates Yeshuos:
It is said in the name of great tzadikim that relating stories of Gedolei Yisroel evoking miracles to provide salvations is a zechus to merit seeing miracles and wonders in our own lives. When we relate these stories, the zechusim of these great men come down to the world and serve to help today’s generation.
It is related that Rav Elimelech of Lizhensk zy”a (quoted by Sefer Sefas Emes of the Brezhaner Rov zy”a, Parshas Beshalach) used this concept to explain the verse in Tehillim (145:7): “Of the remembrance of Your abundant goodness they will speak, and of Your righteousness they will sing.” He explained this to mean that when we speak about the goodness and the miracles that Hashem has performed in the past, more miracles and wonders will be created. He compares this to a wellspring that starts as a small trickle of water and gets bigger and bigger as it flows. The pasuk is thus saying that when we remember Hashem’s goodness, the miracles are again brought back to the world and they begin the cycle once more.
