Absolute trust in God grants a person complete stability, acting as an ultimate shield against any downfall. God alone serves as the sole source of strength and salvation [המאירי]. This deep reliance is not blind; rather, it is built on the recognition that God has repeatedly proven Himself as a protector and savior in the past [אבן עזרא]. Because God serves as a secure refuge, a person can rest assured that they will not stumble [ביאור שטיינזלץ].
A subtle shift occurs at this point in the prayer compared to an earlier, similar expression of faith. Previously, the assurance of not falling was qualified, suggesting one might not fall greatly. Now, that qualification is completely removed. This absence points to a much higher and absolute level of trust and perfection, indicating that the individual will not falter at all.
Commentators explain this elevated state of absolute stability in two distinct ways. On a national level, it represents an ultimate promise for the future, guaranteeing that once the nation emerges from exile, they will never stumble again [רד"ק]. Alternatively, this complete stability is understood on a deeply personal and spiritual level regarding prayer. Often, a person prays and worries that God's answer might be delayed. The absolute assurance of not falling clarifies that God hears and brings salvation without any delay, provided the person praying is completely free of sin. The lack of any qualification reflects a state of total spiritual purity, where there is no wrongdoing left to hinder or delay the acceptance of the prayer [אלשיך].
