Christians can be confident in the knowledge that our sovereign God is in control of our unseen future. The answers we seek are not in our hands but in God's. Anyone who is anxious about the future need only hear the words of our Lord: "Do not worry about your life, what you will eat or drink; or about your body, what you will wear...for the pagans run after all these things, and your heavenly Father knows that you need them. But seek first His kingdom and His righteousness, and all these things will be given to you as well. Therefore do not worry about tomorrow, for tomorrow will worry about itself" (Matthew 6:25, 32-34).Read more: http://www.gotquestions.org/palm-reading.html#ixzz2MgGPRMKR
Ask yourself this question and answer honestly: " Does this glorify God or me?" Remember to God be the glory. If the glory is yours you are placing yourself before God and that breaks the 1st commandment.
It's a form of entertainment :P Unless you take it seriously, then I think perhaps it could be a form of idolatry or witchcraft. Remember, we should seek the Lord for these things, not other spirits. A lot of that stuff is silly rubbish and poppycock :P
Divination seeks to disclose hidden knowledge or to foretell events, not as a result of research, but by the interpretation of omens or by the help of supernatural powers. All these practices are an invitation to communication with or possession by demons. Deuteronomy 18:10-12 says: "There should not be found in you [...] anyone who employs divination, a practicer of magic or anyone who looks for omens or a sorcerer, or one who binds others with a spell or anyone who consults a spirit medium or a professional foreteller of events or anyone who inquires of the dead. For everybody doing these things is something detestable to Jehovah".
