Any sponsor is welcome to share a sweepstakes featuring religious themed prizes. Though we occasionally see a sweepstakes for Judaica, the Christian giveaways are by far the most common of the religious prizes.
Many of the Christian sweepstakes appear in the Books category. Not surprisingly, some of the good books are indeed Bibles. However, life lesson self help books and Christian romances are also popular. ChristianBook always has a number of sweepstakes running and their selections tend to by Bibles, study guides, and self help books. If you are looking for inspiring reading material, this site has lots to offer you.
The Christian romances usually show up on the authors website, or on a site like GoodReads. GoodReads gives away tons of books in all sorts of categories – they are not limited to only a Christian readership.
There are also sites that specialize in Christian rock, mostly notably JesusFreakHideout. This site frequently gives out CD's, t-shirts and prize packs for Christian rock artists. They aren't the only Christian music site, but they definitely have the coolest name.
Sometimes, however, a name can be deceiving. The Hollywood Jesus site does give away some religious themed prizes, but they also have non-secular prizes like new release DVD's. On the other hand, some sites just happen to have Christian themed prizes, but you wouldn't know it unless you visited. A site like Oriental Trading Company has a huge array of decorating pieces and party favors ranging from Mardi Gras, to VBS awards, to baby shower goodies.
You'll also find sweepstakes offering prizes from Christian Seratos and Christian Louboutin that would not be considered as religious themed at all.
