It’s also possible that you would prefer to marry a church member because of shared ideology and how that would make your life easier, but before you jump into marriage, there is the dating phase where things can go awfully wrong. For instance:
Imagine that in private quarters, your boyfriend or girlfriend is still speaking spiritual lingo. You complain about how you had a bad day, and they are quoting scriptures about gratitude and the power of the tongue. You want to gist, but they want to do Bible study and prayer. All the cute things you imagined relationships to be have evaporated, and you are in church 24/7.
