I have never encountered it before, but I have been told similar things before…accused of sincerity.  Oh, and accused of being “enthusiastic” also.  I cried when someone said that to me with the intent to injure me…until Mama directed me to go read the definition.  It literally means “filled with God, infused with God”.  I have proudly been sincerely enthusiastic ever since, in the most intentional of ways. 🙂
