When a man is regenerated, he becomes altogether another and a new, man. While his appearance and his speech are the same, yet his mind is not; for his mind is then open toward heaven, and there dwell in it love for the Lord, and charity toward the neighbor, together with faith.
It is the mind which makes another and a new man. The change of state cannot be perceived in man’s body, but in his spirit. When it [the body] is put off then his spirit appears, and in altogether another form too, when he has been regenerated; for it has then a form of love and charity with inexpressible beauty, in the place of the earlier form, which was one of hatred and cruelty with a deformity also inexpressible. –Arcana Coelestia, Section 3212
