As my faith journey unfolds I am learning that our intangible spirit connects us with higher powers and higher intelligences from higher dimensions (beyond our 3 dimensional world).
It is in our spirit that we "hear" or actually discern the "living word" behind the "written word". Our spirit facilitates higher learning where we come to "know" and understand things over and above what we learn through our 5 senses.
Watchman Nee (1930-1972) explained the spirit has three main functions or attributes: conscience, intuition and communion (fellowship).
