Except a man be born again, he cannot see the kingdom of God. (John 3:3)
Our Lord Jesus Christ taught that the new birth is so important that no one can see heaven without it. Mistakes concerning this doctrine have been very destructive to the Church of Christ. Regeneration, or the new birth, is a work of God. It is not a work of man. It is not something that man does but something that God does. The new birth is a change wrought in us, not an act performed by us. This is stated so beautifully by the Apostle John when in the first chapter of his Gospel he speaks of the children of God as those “which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God” (v. 13).
