Believing in Imam Mahdi (a.s.) gives one vitality and enthusiasm
Hope will lead the people to endure, to open up the path ahead and advance. When you are told to await, it means the present sufferings are not going to last forever. You see, how this makes one enthusiastic and hopeful? This is the effect of believing in the reappearance of Imam Mahdi (God’s peace and mercy be upon him and our souls be sacrificed for him). This is the effect of the belief in the Promised Mahdi (a.s.). This belief has helped the Shia over many years to surpass all the obstacles so today, thanks be to God, the flag of dignity of Islam and the Quran is in your hands—the Muslims and [particularly] Shias of Iran. Wherever this belief exists, the same hope and fighting exist, too.
