How do we know God's mercy is vital for our hope?

In Lamentations 3:22, it is clearly articulated that it is only through God's mercies that believers are sustained and not consumed. This establishes a foundation for hope, showing that it is not our actions or moral standing that preserves us, but rather God's unmerited favor. Recognizing ourselves as sinners in need of His mercy compels us to turn away from self-reliance and to rest in God’s gracious provision. The faithful God does not abandon His people, reinforcing our assurance that His mercy is the lifeline of our hope.
