In Isaiah 50:1–3 the Lord addresses his people’s accusations that he had forsaken them (Isaiah 40:27; Isaiah 49:14). He wants to move them from blind ignorance of the reason for their estranged relationship with the Lord to the understanding that their hard circumstances were the fruit of their own iniquity, rebellion, and distance from God.
God disciplines those whom he loves, yet when we as God’s children are under his discipline, or when we feel distant from God, we can never ascribe fault to him.1
1 Thus says the LORD: “Where is your mother’s certificate of divorce, with which I sent her away? Or which of my creditors is it to whom I have sold you? Behold, for your iniquities you were sold, and for your transgressions your mother was sent away.
