What does it mean to be shut in by God?

To be 'shut in' by God, as illustrated in the Exodus narrative, signifies the condition of helplessness that prompts individuals to recognize their need for divine intervention. God leads His people into situations where they realize their inability to save themselves—much like the Israelites found themselves trapped between the Red Sea and Pharaoh's army. This shut-in experience compels them, and by extension all sinners, to cry out for mercy, acknowledging that only God has the power to redeem. It is through this desperate recognition that one comes to Christ, seeking salvation in His grace alone, rather than through self-righteous efforts.
