In this series we are taking a deeper look at anxiety by integrating the neurobiology, neuroscience, psychology and theology of anxiety. I will also illustrate the different sources of anxiety, ranging from chemical imbalances and psychological factors to demonic spirits that come to torment with a spirit of fear. In this first message I will give a rationale for this study and also lay a foundation with regards to various Hebrew and Greek words associated with anxiety. I'm also going to contrast anxiety with fear, explaining the difference.
