Imam in this regard has undertaken very serious and useful discussions in his famous book "an exposition on Forty Hadith" in this regard as following:
Moreover, He has sent His messengers and prophets and His Books as well to show us which path is right and which one is wrong, which path leads us to Heaven or Hell.
Observance of His commands, or transgressing them does not make any difference to Him, it is for the sake of our own benefit that He has enjoined good and forbidden indecencies.
While remembering all these and various other favors, whose reckoning is beyond the powers of human beings, do we not see that respecting and obeying such a Benefactor is essential for us, or does our reason approve of the acts of violating His commands?
This is an evident fact that we respect great people and those older in age.
This is also true that people respect the wealthy and powerful persons, and rulers and kings, since they are recognized as great.
Can their greatness be matched with the grandeur and magnificence of that King of kings, in Whose kingdom this world of us is merely a particle of dust. He is the Creator and King of this vast cosmos, whose infiniteness cannot be measured or even conceived by human intellect.
Human being, a creature crawling on one of the smallest planets miserably fails to grasp the extent of his own small world, whose sun cannot be compared with far greater suns of innumerable galaxies, Imam further explains.
Our solar system is nothing as compared to lesser several other solar systems, which still elude the keen eyes (and refined telescopes) of great explorers and investigators of the world. Is that Greatest of the great, who can know and cover not only minute details of these known worlds, but of many more unknown worlds, in a twinkling of an eye, is not venerable according to the dictates of reason, as well as in the light of the great book of nature?
