As the corruption of our nature shews the absolute necessity of regeneration, so the absolute necessity of regeneration plainly proves the corruption of our nature; for why should a man need a second birth, if his nature were not quite marred in the first birth?
Thomas BostonBelieving, 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 BostonThe regenerate man's desires are rectified; they are set on God himself, and the things above... Before, he saw no beauty in Christ, for which he was to be desired; but now he is all he desires, he is altogether lovely... regenerating grace sets the affections so firmly on God, that the man is disposed, at God's command, to quit his hold of every thing else, in order to keep his hold of Christ... If the stream of our affections were never thus turned, we are, doubtless, going down the stream into the pit.
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 Boston
