I don't know how devout your friend is in her faith, but I would venture to say that truly devout Christians believe any form of divination to be "devil's work". The Bible practically says so.
The bible also says one should not do the following either but people are not nearly as condemned:
Taken from a recent Facebook post.....
For those that are pointing at the Bible and quoting Leviticus 18:22 - "Thou shalt not lie with mankind, as with womankind: it [is] abomination" - please be sure that you're following the other Leviticus mandates as well:
Round haircuts - Leviticus 19:27 reads "You shall not round off the side-growth of your heads nor harm the edges of your beard."
Football & Bacon - Leviticus 11:8, which is discussing pigs, reads "You shall not eat of their flesh nor touch their carcasses; they are unclean to you."
Polyester, or any other fabric blends - Leviticus 19:19 reads, "You are to keep My statutes. You shall not breed together two kinds of your cattle; you shall not sow your field with two kinds of seed, nor wear a garment upon you of two kinds of material mixed together."
Shellfish - Leviticus 11:10 reads, "But whatever is in the seas and in the rivers that does not have fins and scales among all the teeming life of the water, and among all the living creatures that are in the water, they are detestable things to you."
In fact, there are 76 things that Leviticus says you can't do. It's quite a list, and while some things would be easy to skip, others I'm guessing have been done on the daily for some people.
