Why is it important to be born again according to the Bible?

Jesus teaches us in John 3:3 that 'except a man be born again, he cannot see the kingdom of God.' This rebirth is a work of the Holy Spirit, who transforms a person's heart from spiritual death to life. In this process, individuals become part of the church, represented as Zion in scripture. This idea emphasizes that God must quicken our souls, creating in us a desire to follow Christ and seek His righteousness. A personal acknowledgment of Christ's work in our lives is central to the Christian faith.
