What does it mean to be born again or have a new birth?

To be born again refers to the spiritual transformation that occurs when God imparts new life to a believer through the Holy Spirit. In John 3:3, Jesus tells Nicodemus, 'Unless one is born again, he cannot see the kingdom of God.' This new birth is not a result of human effort or decision but is a divine act (John 1:13) initiated by God. It indicates a radical change of heart and understanding, enabling individuals to see and embrace the truths of the gospel. This transformation empowers believers to receive Christ and claim their identity as children of God, highlighting that spiritual regeneration is exclusively a work of God's grace.
