You've setup the Twitter application for "www.christianfaithwalk.com/home/" and visited it at "christianfaithwalk.com/home/". Notice the www is missing? This means the URL is not valid. You need to authorize the non-www version in your Twitter application or you need to setup an htaccess URL rewrite/redirect to send users to the www version of your site.

There's no need to setup multiple applications. You can actually validate multiple address for a single application. Navigate to dev.twitter.com/apps and click your application (after logging in). Then "@Anywhere Domains" and add as many as you want. CB Connect uses their @Anywhere JS API.
