Effects of Imam existence in the system of creation

The mere existence of the Imam in the system of creation has effects that have been considered in hadith texts. Due to the absence of the Twelfth Imam and making doubts about the benefit of the Absent Imam by the opponents of Shiism, familiarity with the effects of the mere existence of the Imam will increase the knowledge of the believers and strengthen their beliefs. One of the most important effects of Imam's existence is that he is a mediator in divine graces. The following article, aftere terminology of the word "grace", and explaining the position of the Imam as a mediator of divine grace on the servants, presents several cases of mediation. Examples include mediation in the survival of the Cosmos, the security of the inhabitants of the earth, the elimination of torment from the people of the earth, the survival of the opportunity to reform, the descent of heavenly blessings, and the departure of earthly blessings. The author tries to explain each of these titles by using the verses and hadiths of Ahl al-Bayt and with a descriptive-analytical approach. In this method, unlike the theological method, which relies more on rational and logical arguments, relied on hadith and revelatory sources.
