The absolute trust that the ancestors placed in God serves as a powerful model for how pure faith leads directly to salvation. There is an unbreakable link between relying on God and being rescued by Him from life's greatest troubles [רד״ק, ביאור שטיינזלץ, מצודת דוד].
This deep reliance on God was a constant and intense state of being. The ancestors placed their faith entirely and exclusively in Him time and time again, never leaning on any outside forces or alternative solutions [רד״ק]. This steady belief extended across vastly different life circumstances. They maintained their strong connection to God during times of peace and comfort, and they held onto that exact same trust when faced with severe crises. Because of this unwavering consistency, they earned His protection [אבן עזרא].
The sheer power of this belief was so great that it stood on its own, even without spoken words. In stark contrast to a person who must cry out to God day and night in distress, the ancestors achieved their freedom from Egypt through the strength of their pure faith alone, without even needing to voice a formal prayer [אלשיך].
