Before God punishes sinners, He pleads with them to bring them to repentance. The grace of God is like a fountain of living waters forsaken by the Israelites, instead “they hewn themselves cisterns that can hold no water” (v13). This is similar to many Christians, that after knowing Jesus Christ, they look for other worthless ways that cannot save.
“Is Israel a servant? Is he a homeborn slave? Why is he plundered?” (v14). We are God’s people, and for this purpose we are born to serve and worship His holiness.
God bless you.
