How do we know that being born again is essential for Christians?
Answered in 2 sources
Being born again is essential because it transforms believers into new creations, granting them a new identity in Christ.
The necessity of being born again for Christians is rooted in the transformative work of the Holy Spirit. According to 2 Corinthians 5:17, those in Christ become new creatures, indicating a profound change in identity and purpose. This change equips believers to live not for earthly desires, which are temporary, but for eternal realities. The new birth is the beginning of God's work to prepare His children for glory, instilling in them the spirit of adoption as children of God, as referenced in Romans 8:15.
