What does the Bible say about God's eternal mercy?

Psalm 136 repeatedly declares, 'For His mercy endureth forever,' highlighting the eternal character of God's mercy. This mercy is not contingent upon human action but is rooted in the unchanging nature of God, who is good. As established in this psalm, God's mercy has no beginning and no end; it was present before creation and will be celebrated throughout eternity as the theme of praise for His people. This assurance brings hope and peace to sinners, as God's eternal mercy confirms that His grace is sufficient for our failures and needs.
