Religion throughout early history was a primary phenomena which culture centered upon....many of the great communities were founded as religious destinations such as the Stonehenge complexes. Most of what we see today in archeology concerns religion, which those cultures had as the focus of their laws and government. Religion was the center of life and the center of the civilizations....even Christian Europe and the Moslems did not even come close to the pervasiveness of religion into their daily lives.
But if we walk in the light, as He is in the light, we have fellowship with one another, and the blood of Jesus, His Son, purifies us from all sin.
