How does spiritual birth occur according to the Bible?

In John 3, Jesus explains to Nicodemus that one must be 'born again' to see the kingdom of God, highlighting the necessity of spiritual rebirth. This new birth is a work of the Holy Spirit, who transforms a person's heart, enabling them to believe in and embrace Christ as Lord and Savior. It is a divine act that shifts an individual from spiritual death to life, establishing a real relationship with God. Thus, the new birth is central to the Christian faith, as it reflects God's sovereignty and grace in the process of salvation.
