The words of Apocalypse which Saint John wrote down in a singular number referring to himself can be focused on his sense of vision and of hearing as well as on his entire person. The visionary from Patmos takes vividly part in the mystery of God that reveals Himself. At the request of God he records what he has seen and heard. He describes his experiences in heavens. In the future, these experiences will impact on the occurrences on the earth. The above piece of writing may constitute a good prelude for a significant monograph on Saint John and on his experiences with regards to his relation with God.
