I'm sure you mean well.. but that is not helpful at this time.
If you've never dealt with this sort of thing, saying "oh gee, Jesus wants you well" isn't helpful at all.
Maybe you can just try to be supportive?
MA.. I have been in those shoes.. they are uncomfortable. I'm hugging you. New shoes are on the way! (may take a bit of time.. but they're marvelous when they arrive.)
And, I agree with you about not saying anything that I hadn't either said first, or be willing for that person to hear. It's difficult, at best, but a worthy goal!
