For we ourselves were once foolish, disobedient, led astray, slaves to various passions and pleasures, passing our days in malice and envy, hated by others and hating one another. But when the goodness and loving kindness of God our Savior appeared, he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit, whom he poured out on us richly through Jesus Christ our Savior, so that being justified by his grace we might become heirs according to the hope of eternal life.
Regeneration consists in a radical change of heart, for there is implanted a new disposition as the foundation of all holy exercises; the mind being renovated, the affections elevated, and the will emancipated from the bondage of sin. — Arthur W. Pink (c.1886-1952)
