It is very easy to drag a society into pessimism. If someone says “we are ruined” then all other people would sink into pessimism, but if someone revives them, then the mood of these people can easily be changed. Hazrat Mahdi (as) is assigned by Allah for this task. He will revive everyone. After Hazrat Mahdi (as) passes away, the Prophet Jesus (as) will lead. However, after the Prophet Jesus (as) passes away, there will be no one who will be a pillar of society. - Harun Yahya
