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 BostonWhoever be the instruments of any good to us, of whatever sort, we must look above them, and eye the hand and counsel of God in it, which is the first spring, and be duly thankful to God for it. And whatever evil of crosses or afflictions befalls us, we must look above the instruments of it to God.
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 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.
