Two effects among the great effects of believing in Mahdawiyyah
On the matter of the birth anniversary of his excellency [Imam Mahdi], and the belief in this truth, if one investigates and searches in two directions or areas, they will notice great results: Firstly, in the spiritual and mental aspect with regard to closeness to God and individual development of humans. The person who believes in this cause-since they build spiritual relation with the center of divine blessings, the pivotal point and core of God's mercy, will have a better opportunity for enjoying the means of spiritual development and closeness to God. That is why, the people of wisdom, in their spiritual supplication, constantly consider him and give special attention to his excellency. Spiritual bond, remembrance, and attention to the manifestation of God’s mercy, power and justice will itself lead humans to growth and elevation, and provides them with the means of progress in spirituality and wisdom.
The second aspect is in the social and public life and what relates to the collective fate of nations and humanity. In this arena, believing in Imam Mahdi (a.s.) and his reappearance represents a great resource from which nations can benefit a lot. Imagine a ship in a stormy sea. If the people aboard the ship believe that there is no land around their ship within thousands of miles, and they have limited food and water reserves and limited means for movement, what would they do? Can you imagine that they would take any actions at all to move the ship forward? No! Because they think their death is inevitable, they have no hope to take any measures.
