1. The Israelites were slaves in Egypt, but God loved them. From leaving Egypt and walking in the wilderness to entering Canaan, God has done countless signs and wonders for the Israelites to see. But the hearts of the Israelites have been tempted by Satan, and they always abandon God again and again to serve foreign gods. So, time and time again, God raised the outsiders they served to oppress them, and let them find that what they were oppressed again and again was not peace and happiness. Make the Israelites realize that only the Lord is their God, and can help them and make them return to the God who has always led them.
2. We were originally people who lived in sin and had nothing to do with God. But God loves us, leads us through the church, lets us see God's magical creation work, and lets us experience God's wonderful work for ourselves. So that we can serve and worship God forever. But our hearts, like the Israelites, do not respond to God's work, but to the material world. Therefore, Satan is often deceived by the desires of the body, obeys the selfish desires of the body and serves the body, but the result is pain and misfortune. However, when we turn to and serve God, God will give us unexpected peace and joy.
