First, do not bump especially after 23 minutes. People who help here come and go, are volunteers and may or may not be able to help you.
You have a lot of errors here, https://validator.w3.org/check?verbose=1&uri=http%3a%2f%2fwww.pastormarkmitchell.org%2f, some of which could cause your problems. Your posts are in the database so unless something happened to that they are fine.
Turn of all plugins by renaming the plugin folder. Do that via ftp or logging in to your host account. Rename your theme. That will force wp to open with no plugins and with the twentyten theme. If you now see your posts reverse the action, activating plugins one by one until you break it the blog again.
