True recognition of God's absolute uniqueness in the world stems from observing His mighty deeds. His exclusive greatness is revealed through His ability to perform wonders entirely on His own, a reality that will eventually lead to universal acknowledgment of His divinity.
The primary approach among commentators points to a future era. When the nations of the world witness the miracles God performs, particularly the salvation of the Israelites and their gathering from among the nations, a profound shift will occur. They will declare His greatness, abandon their idols, and embrace the absolute truth.
God's greatness lies in His role as the primary cause of all existence and the ultimate purpose of all creation. Furthermore, His capacity to perform wonders demonstrates absolute mastery over the natural world. He is the ruler who can override and break the laws of nature to save those who call out to Him in times of distress [מלבי״ם]. He executes these miracles completely alone, without any assistance or partner, just as He created the heavens and the earth by Himself before the angels even existed [רש״י, אלשיך, מלבי״ם].
This reality highlights a sharp theological contrast between the faith of Israel and the perspectives of other nations. The nations of the world might recognize God's greatness after being amazed by His actions, but they often still perceive Him merely as the greatest among other deities, or they worship secondary forces as intermediaries to honor Him [אלשיך, מאירי]. However, this flawed perspective is completely rejected. God's position is not one of relative superiority, but of absolute exclusivity. He operates without any need for others, and there is simply no other power besides Him [אלשיך, ביאור שטיינזלץ].
