Since 1994, Christian Link has served the community as one of the top Christian search engines on the web.  They also can help design, provide technical support for, promote, and host your site.

ChristSites has a search engine that works by category as well as keyword to save you time finding info on a topic.  The database has somewhat fewer listings, but it contains high-quality sites because each one has actually been rated by a reviewer who visits the site and rates it with consistent criteria.

ChristianWebsite.com contains a large searchable database of Christian sites, all checked out by the company.  In addition to their premier search engine, they offer Christian web hosting and FaithBook, a Christian networking counterpart to FaceBook.

Worthy Links - Christian Search Engine is a search engine that indexes the entire text content of thousands of Christian websites.  Fast searches with lots of hits.
