'Mercy' in the Bible

Blessed [gratefully praised and adored] be the God and Father of our Lord Jesus Christ, who according to His abundant and boundless mercy has caused us to be born again [that is, to be reborn from above—spiritually transformed, renewed, and set apart for His purpose] to an ever-living hope and confident assurance through the resurrection of Jesus Christ from the dead,

Once you were not a people [at all], but now you are God’s people; once you had not received mercy, but now you have received mercy.
