I know many people would value a Bible as a very personal gift and treasure it, many others would not, and might see the gift as an attempt to change her in a way that she is not interested in changing. I don't know how your wife sees the gift. But if you think that it is not something that she is happy with for Christmas, I think you might consider giving her something else in addition. A gift certificate for a massage or a manicure is something a lot of women like. Many of the beauty salons offer those. Just a suggestion. It sounds like she made an effort to be thoughtful of you this year, I do not want to see you throw that away by giving her a gift that she does not value.
