As far as I know, dear
As far as I know, dear Chuck, there are technical reasons for this. Someone may be able to explain. Is far as I understood, the site was moved or rebuilt in 2007 and the old comments are not under the Heavenletters themselves but in some separate compartment (which you can find under "Heavenletter Forums" when you scroll down to the bottom).
Then last year we had a very exciting phase when the "Heavenletter Archives" were completed (mainly by Heaven Archivist Annette who did a wonderful job and made me very happy) and all the extant Heavenletters finally became accessible. In the course of this process, many Letters had to be renunmbered, and it seems to me that the comments on the renumbered Letters, or some of them, are gone.
Anyway, the fact that there are so many Heavenletters without comments does not mean that no one ever wanted to or did comment on them. Like you, I felt a little shy at first to post a first comment, but when I saw all those beauties, I simply couldn't help it. It's so nice that you and some others are doing it too.

The letters from God are my first thought in the morning, my constant company during the day, my bread, my breath, my light and so much more. I read and read them again, I cry with them, I laugh with them, I keep expanding my vision. I have no words to thank you. God is teaching me to fly!
