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.
