How does God's mercy endure forever according to the Bible?

The concept of God's enduring mercy is vividly expressed throughout the Scriptures, particularly in Psalm 136, which repeats, 'His mercy endureth forever.' This declaration reassures believers of God's unceasing compassion and faithfulness, regardless of our circumstances or failures. God's mercy is rooted in His character, asserting that He is always willing to forgive and restore those He has chosen. This everlasting mercy underscores the hope of salvation, as it is not dependent on our works, but on His grace and sovereign will to make us His own.
