In regeneration, the mind is enlightened in the knowledge of spiritual things... The will is renewed... The will is cured of its utter inability to will what is good. While the opening of the prison to them that are bound is proclaimed in the gospel , the Spirit of God comes to the prison-door; opens it; goes to the prisoner, and, by the power of his grace, makes his chains fall off; breaks the bond of iniquity, wherewith he was held in sin so as he could neither will nor do anything truly good; brings him forth into a large place.
