What does it mean to be 'shut up to Christ'?

Being 'shut up to Christ' refers to a spiritual state where one realizes the futility of self-reliance and becomes utterly dependent on Christ for salvation. In the sermon, this concept is illustrated through Joseph’s actions during the famine, where he gradually stripped the Egyptians of their resources until they had no other choice but to turn to him for sustenance. Similarly, God employs trials and hardships to lead His elect to the end of themselves, causing them to seek salvation exclusively in Christ. This work of stripping is part of God's redemptive process, leading to a reliance on the grace provided through Christ, as seen in scripture such as Psalm 34:6.
