How does the Book of Judges illustrate human depravity?

In Judges, we observe Israel's continual rebellion against God, which serves as a stark reminder of human depravity. Despite witnessing God's mighty works, the Israelites repeatedly turned to idolatry and disobedience. This illustrates the sinful nature inherent in all humanity, as Romans 3:23 states, 'for all have sinned and fall short of the glory of God.' The recurrent theme of Israel's failures emphasizes our need for a savior, which is fulfilled in Christ. His grace provides the remedy for this depravity, ensuring that salvation is wholly a work of divine mercy rather than human effort.
