Why is being born again necessary for Christians?

The necessity of being born again is a cornerstone of Christian doctrine, highlighted in John 3:3 where Jesus said, 'Except a man be born again, he cannot see the kingdom of God.' This new birth is a work of the Holy Spirit that brings about a radical inner transformation, turning individuals from a state of spiritual death to life. For Nicodemus, a respected religious leader, this concept would have been striking, as it shows that even those steeped in religion must undergo this divine change to grasp the truth of the Gospel. This supernatural rebirth enables believers to receive and embrace the truth of God’s love, allowing them to live in the freedom of grace and to ultimately inherit eternal life.
