As for the Imam of the Time (may God hasten his reappearance and God's greetings b upon him), the first point is that the great personality is the inviter to God. Looking at that great Imam (a.s.) is a way of expressing one's love for and obedience to Allah the Exalted: "greetings be upon you who invite to God and who are conversant with His signs" [Ihtijaj, Vol.2, page 493]. All matters, all prophets, all saints, all sanctities and all pure souls who cast light on our lives, on our world and on the entire universe are the signs and reflections of God. This is a point that should receive attention. We pay attention to the Imam of the Time (a.s.), and we appeal and show humbleness before that great Imam (a.s.) so that this humbleness reaches the Essence of the Only One and so that we show our obedience to Allah the Exalted.
Belief in the Imam of the Time (a.j.) is a component of religions’ worldviews. That is, just as divine religions hold viewpoints within their general worldviews about the universe, mankind, origin and the end of human life’s trajectory—about genesis and resurrection—they also hold viewpoints in their worldviews about the final destination of the caravan of humans.
A worldview is a great system which lays the foundation for all the thoughts, obligations and rules of religions. It addresses the issues of the afterlife and the hereafter. Another issue is where the mankind is heading to. If we liken the human community throughout history to a caravan which is taking a specific path, then we are faced with this question: Where is this caravan going? What is the destination of this caravan? What is the end of this path? This is a serious question and every worldview should answer it. Religions have answered this question... all of them believe that this caravan will reach a favorable, sweet and pleasant destination in the end.
The main characteristic of this destination is justice. Justice has been humanity's general request from the first day until today and it will remain mankind’s main request until the end. Those people who try to believe in variety, diversity and change in their principles and main philosophies cannot deny the fact that humanity has had certain requests from the first day until today, the most important of which is justice. Humanity is after justice. It has never changed its mind about this demand and in the end, this demand will be met.
