How do we know God's grace is evident in the story of Judah and Tamar?

The narrative of Judah and Tamar is a striking illustration of God's amazing grace. Despite the sinful choices and failures of Judah, including his wrongful judgment of Tamar and his retreat from righteousness, God orchestrates His plan of redemption. The genealogy in Matthew highlights Tamar's inclusion, showing that God can redeem even the most scandalous situations for His glory. This affirms that grace is not only for the righteous but also for wretchedness, emphasizing the message of Romans 5:20 that where sin abounded, grace did much more abound.
