Hi, can anybody help? I've recently been reading article’s on things like NLP (Neuron-linguistic programming) Law of Attraction and books like Anthony Robbins, physics etc. For example a close friend of mine is very heavily in to NLP, Psychology, the power of the mind etc. He attends NLP seminars regularly and whilst i firmly believe that some of these subjects have a certain amount of truth to them and to an extent can have an effect on our lives, i still can't help believing that the Bible is the gospel the source of all knowledge and truth nothing else. It seems that my friends core beliefs are in NLP and the law of attraction, i find this greatly misleading similar to the concept of scientology because its obvious that salvation doesn't lie in either of these concepts. However with regard to the information in this post where in the bible can I find where GOD talks about the body and mind and what one must do in order to be the best of one's self to produce the best results. I feel as though the real truth could help my friend in having an eternal life instead of a mortal one.Thank youMusicworld.
