Believing, repenting, and the like, are the product of the new nature; and can never be produced by the old corrupt nature... as the child cannot be active in his own generation, so a man cannot be active in his own regeneration. The heart is shut against Christ: man cannot open it, only God can do it by his grace.
Thomas BostonO what hardness of heart mayst thou see in every corner whither thou goest, and where thou preachest, most part being as unconcerned as the very stones of the wall; and say what thou wilt, either by setting before them alluring promises or dreadful threatenings, yet people are hardened against both, none relenting for what they have done, or concerned about it.
Thomas BostonPersuade yourselves, that the faith of the gospel is beyond the power of nature; that there is a necessity of a power from on high to bring you to believe. This will raze the old foundation, and cause you to look up for it.
Thomas BostonIn 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.
Thomas BostonAgain, the glory of one attribute is more seen in one work than in another: in some things there is more of His goodness, in other things more of His wisdom is seen, and in others more of His power. But in the work of redemption all His perfections and excellencies shine forth in their greatest glory.
