Regeneration is the ministry of God the Holy Spirit who creates a human spirit in the believer, making him a new spiritual species (John 3:6; 2 Cor. 5:17; Gal. 6:15).
The human spirit is the immaterial part of man that enables him to understand spiritual phenomena (1 Cor. 2:14).
Regeneration is necessary because man is born spiritually dead (Eph. 2:1; Rom. 5:12).
Regeneration is eternal; it cannot be lost (John 10:28–29).
Regeneration is the basis for the royal family of God in the Church Age (John 1:12–13).
