Here is a video produced by IVP from 1989 about the New Age movement. Please take the time to watch it for these issues are still with us.
There is a great difference between the wisdom of the world and God's Wisdom. This is the aim of Christian Apologetics; to learn God's Wisdom in order to out-think the world for Christ.
Two authors interviewed here are Doug Groothuis and James Sire. I would recommend Doug's book Unmasking the New Age and James Sire's book Naming the Elephant; both of these books are excellent, and accessible reads to help you clarify and strengthen your Christian walk and defend your faith.
