What does the Bible say about the necessity of regeneration?

The necessity of regeneration for spiritual life is emphasized throughout Scripture, particularly in John 3:3, where Jesus tells Nicodemus, 'You must be born again.' Regeneration is the work of the Holy Spirit, which enables a person to have faith in Christ. As stated in the sermon, it's not simply a matter of reformation or turning over a new leaf, but a fundamental spiritual transformation that is essential for faith and salvation. Without this supernatural birth, individuals remain in their natural state of unbelief and sin.Thus, the importance of regeneration cannot be overstated in the context of salvation and the Christian life.
