Religion

Non-believers quoting scripture are typically told that they don't understand the Bible, and that only believers can properly discern what it means.

That's just an excuse, though, of course. Those who are already ignoring scriptural guidance will just continue doing so.

You can quote the supposed words of Jesus, himself, to some, and they will come up with an excuse for not behaving the way their supposed Savior advised.

Still, it is useful to quote scripture to make a point about things, particularly hypocrisy, which runs rampant in evangelical circles. They won't listen, but others might.
