How do we understand the need for regeneration?

Regeneration, or the new birth, is a work of the Holy Spirit that changes a person's heart and enables them to respond to the gospel. John 3:3 states, 'Unless one is born again, he cannot see the kingdom of God,' highlighting the necessity of spiritual rebirth. This transformation results in a new nature, allowing the individual to embrace the truths of the gospel and live in a way that is pleasing to God. Regeneration affirms that salvation is entirely initiated and sustained by God, ensuring that all who are truly saved are new creations in Christ.
