What does it mean to be born again from a Reformed perspective?

From a Reformed perspective, being 'born again' signifies a radical transformation initiated by God, which is essential for salvation. This regeneration is a work of the Holy Spirit that enables individuals to respond to the Gospel. The Bible makes it clear that while we were dead in our sins (Ephesians 2:1), the Spirit grants us new life—a gift of grace that we cannot produce ourselves (John 1:13). This doctrine highlights divine sovereignty, affirming that it is God who calls, quickens, and grants faith, illustrating that our spiritual rebirth is a result of God’s sovereign choice and power.
