Knowledge of G-d in the Messianic Era

At the end of Rambam’s “Mishneh Torah”, he teaches the main principles of Moshiach and the Messianic Era in Torah Law. He concludes with the prophecy in Isaiah 11:9 about the Messianic Era. “The earth will be filled with the knowledge of G-d as water covers the ocean bed”. Chassidic teachings explain that in that time, we will see that all things are constantly created by G-d from nothing.
