How do we know that the new birth is essential for Christians?
Answered in 1 source
The new birth is essential because it is the means by which believers are regenerated and empowered to live a godly life.
Jesus emphasizes the necessity of being born again in John 3:3, declaring that without this spiritual rebirth, one cannot see the kingdom of God. The regeneration of believers creates an inner transformation that aligns them with God's will, enabling them to put off sinful behaviors associated with the old man and embrace a new life marked by the fruit of the Spirit (Galatians 5:22-23). It's this new birth that not only justifies but also sanctifies believers, equipping them to live in a manner worthy of their calling. Thus, the new birth is foundational to Christian identity and practice.
