The physical world feels solid and enduring, but its stability and the ongoing rhythm of life are not automatic. Instead, the steady ground beneath our feet and the continuity of existence rely entirely on the constant will and promise of God. Time moves forward and the reality around us constantly shifts, yet the basic foundation of the earth remains firm due to His careful watchfulness. The primary approach among commentators is that God's faithfulness is an expression of His deep loyalty, the keeping of His promises, and the absolute strength of His will [ביאור שטיינזלץ, מצודת דוד, מאירי]. A deeper perspective adds that this very faithfulness is the actual presence of God resting upon the earth, serving as the hidden force that grants the world its continued existence [חומת אנך].
As time flows, the temporary nature of all living things becomes clear. Unlike the stars and heavens that remain forever, human beings and all other earthly creatures are born, live out their days, and eventually pass away. Yet, God's promise guarantees that while individual lives come and go, the species themselves will never disappear. The world is built to last through a continuous chain of generations [מלבי״ם, מאירי, אבן עזרא].
This enduring promise is the only reason the earth is firmly established. The stability of the ground is not the result of independent laws of nature, but rather the direct outcome of God's spoken word. In a purely natural state, the waters of the sea should completely cover the globe. The fact that dry land remains exposed and stable is an ongoing miracle that depends solely on a Divine command [אלשיך]. Because God alone founded the earth and sustains it through His word, the entire world remains completely under His control, and nothing can prevent Him from doing exactly as He pleases with His creation [מצודת דוד].
Ultimately, the earth stands with absolute, unshakable stability. From a cosmological viewpoint, the earth rests as a fixed central point within the surrounding heavens. It remains perfectly in place without shifting or tilting. Because of this perfect physical balance, the fundamental rules of the world stay firmly rooted and permanent, providing a reliable home even as the creatures living upon it are constantly renewed [אבן עזרא, מאירי].
