At a certain point, after reading some kinds of books or meeting with some people, when we start looking back into our life, as I believe many of us do because of the curiosity we have within ourselves to know the way or the circumstances that built our ways to pursue the kind of life we have lived or reached so far, we start comprehending that how exactly our steps were shaped for the life we were destined to, and we get to know that in past when we were encountering those moments, we were not aware of those specific steps that would lead us to the experiences we are having right now, and at that point, we get to know that there was a kind of force so powerful that it drove inside ourselves an inclination which helped us pave the path towards our destination, and eventually we start believing in a supernatural power, which in our religion is, of course, our Almighty Allah. 

The realization of this power only comes after we start self-analyzing, and after we start knowing that there is someone who knew us at the time when we were unaware of ourselves even of an inch and made us incline towards the path we were suitable of the most. 

The need for this introspection induced God-realisation is important to build our self-esteem higher than what we think of it at every point we get judged, this build in us the self-confidence that helps us confront almost every sort of threat that intimidates us of being lonely.
