How do we know that God's mercy is everlasting?

The assurance of God's everlasting mercy is rooted in Scripture, particularly in Jeremiah 31:3, where God declares, 'I have loved thee with an everlasting love: therefore with lovingkindness have I drawn thee.' This enduring mercy is not based on our faithfulness but on God's unchangeable character. Throughout the biblical narrative, we see God's persistent mercy despite human rebellion and unfaithfulness. He continues to call His people back to Himself, much like Hosea’s love for Gomer symbolizes God's unwavering love for Israel and, by extension, His church.
