What does the Bible say about the new birth and being born again?

Scripture emphasizes that being born again is a transformation that allows believers to enter into a new relationship with God. In 1 Peter 1:23-25, we see that we are born of incorruptible seed through the Word of God, establishing our identity as God’s children. This new birth is the foundation for unfeigned love toward one another, as true believers are born of the same Spirit. The love we exhibit is not merely a sentimental feeling but a profound bond stemming from the shared experience of grace and the knowledge of God through Christ.
