As a christian I'm not a fan of divination of any sort. Regardless of whether someone is trying to talk to God or the devil. I can see why someone would be frustrated by Christians who condemn one sort of divination and then seek to use another form of divination. Because both efforts seem to come from the same completely understandable desire for an experience or knowledge that will bring peace.*
Nonetheless, I avoid divination for five reasons:
1. Divination almost altogether ceased in the new testament after Pentecost and the descending of the holy spirit onto believers.
2. Revelation is powerful and that which is powerful is dangerous. I feel much more comfortable with revelation that has been examined and tested for at least 2000 years than with the words uttered by a prophet yesterday or random words that came to my mind during prayer this morning. I've seen people's lives manipulated and controlled by the power of divination and I find it pretty disgusting when that happens.
3. I have found the spiritual counsel of the bible to be sufficient for most any question I have. Moreover, the bible answers all the BIG important questions and any smaller questions I might have are just extrapolations of answers to the big questions. Questions with answers that can't be extrapolated from biblical answers simply aren't as important as I think they are.*
4. Some people might find it ironic, but I'm also against divination BECAUSE I believe in Christian liberty. I believe that anything that isn't required by the bible is open for my own judgement. I'm not interested in being bound by more rules than are in the bible. I believe divination is often an effort to be bound by additional revelation. I think everyone can agree that the bible has enough rules. Another way of saying this is to quote saint Augustine: "Love God and do what you want." Of course I personally believe that loving God precludes divination.*
5. The bottom line is that for the Christian peace should not be sought from experiences to come or from knowledge about the future. Rather it should be found in the knowledge of one's relationship with God and rituals and practices that celebrate that relationship formed during the death, burial, and resurrection of Christ. Christians don't need outside revelation for peace as we have the holy spirit himself within us to testify to our hope.
