I believe human activity occurs within the context of a great spiritual battle between good (God and His heavenly host) and evil (Satan and his minions). The spiritual battle is mostly invisible to us, but it sometimes manifests itself in the battle between countries, ideologies, ideas, religions, and other areas. The spiritual forces of evil are not permitted to interfere with human free will most of the time, but they try to influence people’s behavior/actions so that they end up doing their bidding or following them. Therefore, an understanding of the spiritual battle and an understanding of earthly phenomenon (the social sciences and the physical sciences) is necessary to understand what is going on and what is likely going to happen in the future. Only understanding what you can visibly see or what you can hear severely limits your ability to understand the big picture completely. You will completely miss out on understanding the context in which events are happening (or will happen) and why events are happening (or will happen).
Therefore, I believe a person must consider secular and spiritual/religious events/developments to fully understand ongoing current events and to anticipate what is likely going to happen in the future. More specifically, I believe a person needs to be knowledgeable about Bible prophecy, the interaction between the fields of economics, finance, and politics, and scientific/technological developments.
