First of all, sorry if I cannot correctly express the original expression used in my native language to ask for the "spiritual condition".
A few years ago some member of the family asks my wife directly how is her "spiritual health" (for me it's one of the many strange vocabulary used by JW like "the slave says..."). She was catched by surprise with the direct question and says that everything is ok... and luckily someone call them for lunch.
my question is: Do you have any good answers for that question? You can be ironic/use some humor because the question is a little bit anecdotical
