Here is a website I recommend where there is a wealth of information on New Age practices, books and activities that have crept into many of today’s churches. Marcia Montenegro is an ex-astrologer and new ager who left all that and became a Christian. Now she is writes books and articles warning of what she sees creeping into Christians lives and the church. What does Yoga, the Ennagram, Jesus Calling books & devotionals, contemplative spirituality & breath prayers have in common among many other things? They are all of the New Age that have their basis in the occult. http://christiananswersforthenewage.org/
