Apostle John was on the island of Patmos (A place of extreme hardships) when he received the Book of Revelation.
John experienced such mighty revelations about Jesus Christ’s second coming while in a human body. Daniel, who had comparable revelations, became ill for a few days after getting them (Daniel 8:28).
John’s physical body was able to sustain both the hardships on the island of Patmos and the mighty revelations of God.
It is impossible to sustain the impact of such powerful revelations concerning the second coming and to withstand the prison hardships with a human body.
The only way he sustained such powerful revelations and hardships was through resurrected body / power. In history, it is said that Roman emperor Domitian commanded that the apostle John be boiled to death in oil, but John only continued to preach from within the pot. Another time, John was forced to drink poison, but, as promised in Mark 16:18, it did not hurt him.
God transformed Apostle John’s human body into a resurrected body with resurrection power. All prophets in the Bible had 1 or 2 visitations where God took them to heaven but John had many visitations and visited many places in heaven. Only a citizen has access to all of the country’s locations.
With resurrected body, he became a citizen of heaven, subject to the rules and authority of heaven while still living in a human form on earth. Earthly problems and afflictions had no effect on him since he had the power of resurrection, i.e. the power that had risen Jesus from the dead. The earthly body is subject to earthly conditions and authority, whereas the resurrected body is subject to the conditions of heaven and is unaffected by earthly conditions.
God must transform our earthly bodies into resurrected bodies with resurrection power if we are to endure the end times.
Only if our earthly bodies are changed into resurrected bodies, we will be able to withstand the end times.
