Because they don't believe in being born again...They admit they are not saved (as in salvation) but hope to get saved someday, if they do enough good works...
We take them at their word and try to show them with scripture they have been taught wrong...
And worse yet, they submit post after post that what they teach is true and must be adhered to for anyone to have a chance at eternal life in heaven...And they don't even believe in heaven...It's a 'state' of mind...
Don’t forget the blood drinking. Oh and incense burning too. You know what the worst part is? We pass the offering plate twice. :-)
