Re-order posts: Tanzaku theme

I want my posts to show up with the oldest on the upper-left and the newest on the lower-right, as if you were reading a book or newspaper, and text kept appearing in order.

I’ve already switched the order of posts by using
<?php query_posts($query_string . '&order=ASC') ?>
but the posts still display in a cascading style, with the oldest posts in a row along the top, instead of in a column along the left.

I’m using the Tanzaku theme and my website is http://www.bible2.org

Any suggestions are greatly appreciated.
