Imam Khomeini explains the matter in his famous work of "an exposition on Forty Hadith" as following:
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.

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?
If any one fails to do this, he ought to be extra watchful and careful, since God Almighty is present everywhere, and no odd corner of the world can delude his Omnipresent sight. Every living being is within the range of His view and all knowledge is in His infinite attendance, so never forget Him.
A speck of penitence in one’s heart would not melt any person into water, and he would not fall to the ground. Therefore, my dear friend, remember God and remember all His favors and graces, and stop disobeying Him, Imam Khomeini further explained.
Overpower and subdue the satanic band in this great war, and convert the spheres of your mind into divine realm by driving out the satanic legions and inviting the divine hosts, so that God may succor and protect you in the dangers threatening to befall you in this battle.
The battlefield, which is more immense than this one, is the scene of the battle (jihad) against thine own self, the invisible world of within and the second stage of this jihad. We shall deal with this subject afterwards.
By the time, I remind you not to have any expectations from anyone but God. Except Him, the Almighty, nobody can help you. With all humility and with all the tears your eyes can offer (to wash your sins), pray to God and seek His assistance to emerge victorious in this crucial battle.
