We must be born again because, as sinners, we are spiritually dead and cannot understand spiritual things without the new birth.
The necessity of being born again stems from our innate spiritual condition following the Fall. Scripture teaches that each person is born into sin and spiritual death, rendering them incapable of understanding or seeking God without divine intervention (Ephesians 2:1). Jesus stresses the need for a new birth in John 3:3, stating that a person cannot see the kingdom of God unless they undergo this transformation. The new birth is essential for unlocking the spiritual truths of the gospel and allowing one to enter into a relationship with God. Without being born again, individuals remain in their natural state, unable to appreciate or respond to the grace of God.
