And so that those who have been given knowledge will know it is the truth from their Lord and have faith in it, and their hearts will be humbled to Him. Allah guides those who believe to a straight path. (Surat al-Hajj, 22:54)
There are two kinds of people: those who know and so can appreciate Allah's power, and those who do not. The latter lead an ordinary life and die. Throughout their lives, they are reluctant to wonder why they exist or who created them, whether they have any responsibilities toward Him, or the infinite power of our Lord, Who created the entire universe, including them, from nothing. Instead, they busy themselves with such mundane issues as their education, how to get promoted at work, or their children's future. Of course such matters deserve some attention, but it is a great mistake to make them the goal of one's life. Such minor issues hinder people from seeing the countless miracles surrounding them. Furthermore, even if they can see these miracles, they shy away from pondering over them.
Those who feel the urge to get acquainted with the signs of Allah's existence and absolute power, and then begin to appreciate them, lead a totally different life. Out of their strong conscience, they observe their surroundings with awe and acknowledge that He created whatever they see. Aware of their responsibilities toward our Lord, the All-Mighty, they do what is pleasing to Allah, live according to His rules, and, most important of all, realize that each person will be called to account in the Hereafter.
Allah guides the members of the first group. Although they have always remained a minority, their way has always been the right one. Allah relates the difference between these two groups, as follows:
Those who believe in what has been sent down to you, what was sent down before you, and are certain about the Hereafter. They are the people guided by their Lord. They are the ones who have success. As for those who are unbelievers, it makes no difference to them whether you warn them or do not warn them, [for] they will not believe. Allah has sealed up their hearts and hearing, and over their eyes is a blindfold. They will meet with a terrible punishment. (Surat al-Baqara, 2:4-7)
No doubt, being one of these people is a great blessing granted by Allah, for unless otherwise willed by Him, no one can guide anyone else to the truth and the righteous path:
You cannot guide those you would like to, but Allah guides those He wills. He has best knowledge of the guided. (Surat al-Qasas, 28:56)
