What is regeneration?
Regeneration is the secret, decisive work of the Holy Spirit by which a spiritually dead person is born again — given new spiritual life — so they can repent, believe, and follow Jesus (John 3, Titus 3:5).
Jesus told Nicodemus, "You must be born again." Conversion includes our believing, but the deeper miracle is God’s prior work giving the spiritually dead a new heart.
Regeneration is monergistic — God acts alone. We don’t cooperate in being born any more than we cooperated in our physical birth.
Its fruit is observable over time: a new desire for God, hatred of sin, love for fellow Christians, and obedience that flows from a changed nature, not from gritted teeth.
