David is an old soul. He has written hundreds of blog and article on different phases of spirituality. He is a Christian by faith, but not a member of the modern day Christians that the news portrays. His beliefs are from the old world Christianity that focus on love, brotherhood, and education. As such, he has written about many religions other than Christianity and from a point of view that is supportive of individual reader choice. His writings are about your journey not his own.
David has written about metaphysics, crystals, healing stones, meditation, and many other topics within spirituality. His content is open because he believe that God has his own way of reaching out to people and everyone's path in life is their own unique journey. Who is he to mess with that journey?
