After much research I have discovered they are more than fifty countries world wide that are experiencing persecution. Top of the list is Bhutan, North Korea. They are fifty countries that are currently on world watch. 5 are Islamic dominated countries, 4 Have communist regimes in power and bhutan is dominated by Bhuddism. Some of those countries are Laos, Iran, Maldives, Somalia, China, and Afghanistan.
In comforting these persons, Revelations would help them to realise that persecution is supposed to happen and that it is all for the Kingdom of God and that they should take comfort in the fact that Jesus the faithful witness went through presecution and was killed and raised again showing that we too can endure to the end because of what he has done for us. We have eternal life because of him.
