Move Forward as a Spiritual Person.
Paragraph 2 "Robert and his wife began passing time by quizzing each other on Bible subjects. His wife, a spiritually strong person, had no problem answering the questions, but Robert found himself constantly embarrassed, not knowing what to say."
There is no indication of how she fits the template of a spiritual person other than she can answer Bible trivia. Is that simply an effect of her being "spiritual person"? Perhaps her house or car is a mess, but she does great in Bible Jeopardy. Perhaps she is mean and a complainer or spends too much but is good at quizzing.
So he is embarrassed because he does not know the answers to quizzing? Perhaps he is busy working, cleaning, and a good husband. Wouldn't that be better than knowing trivia?
Their focus is not on practical things, but on the organization.
