The first two Judges begin to describe the Judges "cycle." The people forget God, turn to idols, God sends an oppressor, the people cry out to the Lord, and God raises a deliverer who gives rest for a time. Then the people forget God again.
From Othniel and Ehud, we can learn how we can prevent a similar cycle to happening in our own lives. We also are encouraged that our deliverer, the Lord Jesus Christ, brings total deliverance. And unlike the Israelite judges, Jesus lives forever to rescue and preserve his people.
We are challenged by seeing the same kinds of failure in our own lives, but we're encouraged that our deliverer is the Son of God himself.
