Yes, unfortunately, it would. "You can't teach an infidel."
There is, however, some evidence that suggests that periodic little "truth darts" CAN and DO get thru the fog. Using your notes and your spiritual belief, that might be "Honey, do you realize how incredibly sad your foolish decision must make the Lord?"
or,
"If you really want to know if this is right or wrong, you might want to ask yourself -- honestly -- if you have a peace about your boyfriend when you pray about it." (and then walk out)
