Dear close friend.
It is kind of you to let me know that I am in your thoughts. You have always shown yourself to be a true and loving friend. I realize you are sad because I am no longer at the Kingdom Hall and worry about my salvation.
I want to ease your mind, if I can, by saying that I am happy and confident about my future so not to worry. As far as I'm concerned we will always be friends.
Fondly, Daniel
If you want you can invite her to lunch as well. Through the ball in her court if you want but stay off the topic of religion- period!
