So when and how is one quickened - or born again - by the Spirit of God? Is it when one performs a set action required for salvation, or does scripture present that it's by God's sovereign election and choice? Jesus instructs Nicodemus that just as God sovereignty controls and directs the wind when and where He pleases, the children of God are born again in like manner - that one is quickened by the Spirit in accordance with the will and timing of the Son of God.
