How do we know God's mercy is evident in the story of Ephraim?

God's mercy toward Ephraim is vividly illustrated in his acts of calling and redeeming a people who failed Him. In Jeremiah 31:20, God expresses a deep emotional connection to Ephraim, referring to them as 'my dear son' and declaring His intention to show mercy despite their rebellion. This reflects the nature of God's grace, underscoring that regardless of our failures, there remains an avenue of restoration through Christ, who fulfills God's promise of salvation and reconciliation for His people.
