The revelation of God's power in the world is deeply tied to the Israelites' right to their homeland and the sweeping historical events that led to its conquest. A primary approach traces this display of might back to the story of creation. God revealed the secrets of how the world was made to the Israelites to establish a fundamental truth: the entire earth belongs to Him. Because He created it, He holds the absolute authority to uproot nations and settle others in their place according to His will. This revelation served as a preemptive defense. When the time arrived to give the Israelites the lands of the seven Canaanite nations, the rest of the world could not accuse them of being thieves or invaders taking a land that did not belong to them [רש״י, אלשיך].
Shifting the focus from the dawn of creation to unfolding history, other perspectives highlight God's power through the dramatic miracles of the Exodus from Egypt, the journey through the desert, and the eventual conquest of the land. The sheer magnitude of these wonders terrified the inhabitants of Canaan, causing them to retreat and melt away in fear before the Israelites [מאירי]. Furthermore, the act of driving out seven massive, powerful nations to give their land to Israel was such a profound display of God's might that it even surpassed the miracles of the Exodus [רד״ק].
The way God communicated these events took the form of advance promises and prophecy. By directing the course of history, God informed His people of the future long before it unfolded, acting as a direct continuation of the promises He made to the early patriarchs of the nation [ביאור שטיינזלץ]. Announcing these plans ahead of time proved that the conquest of the land was never a random historical accident, but rather a deliberate, pre-planned divine design [רד״ק, מצודת דוד].
On a moral and spiritual level, the display of God's power is also understood as a direct expression of His core traits of kindness, justice, and righteousness. In this view, God commanded His people to follow His ways and uphold His laws, standing in sharp contrast to the corrupt practices of the Egyptians and Canaanites. Maintaining this high moral standard was laid out as an absolute, essential condition for the Israelites to inherit the land [אבן עזרא].
