It is true that hardly anyone seeks God, for human beings are deluded by the mirage of things liked and disliked, and completely involved in either acquiring or avoiding them. Is it any wonder in a world where happiness is so temporal and life so fickle?
There are those who say that they have already achieved knowing God through faith and/or belief, and validate this with spiritual emotion or the quoting of scriptural texts. While this may be good spiritual practice, by itself it is prone to error because it can so easily become a means of denial in which one does nothing but continue to hold on to the same beliefs in the name of Faith.
My own view is that belief is a mental phenomenon. People do it all the time about many things, daily. It is easy. Anyone can do it. Belief is a word used for something a person takes as true. The word ‘faith’, on the other hand, seems to get used as a means of denial—one accepts teachings solely on the basis of their existing belief, which they then call faith, leaving no room for further consideration and nothing more to be done.
This is how it appears to me, based on people I know and have known in the past. Faith saves them from having to go any further, take up any kind of spiritual practice, or deal with any significant changes in themselves or their lives (not to mention keeping their egos in tact).
Belief is a fixed mental state of certainty that something is true. Faith is action related. When one trusts the spiritual teachings of their lineage and puts them into practice, one acts with faith. Real Faith comes when such action ultimately proves the teachings to be true.
This verse is telling us that, of the thousands of people who claim to know God, they do not.
Hardly anyone in thousands seek to know God, and of those who do, rarely does anyone succeed.
In Yoga, faith is the acceptance of spiritual teachings that one then puts into practice through meditation in order to experience the results. The results of personal experience in meditation either confirm one’s understanding or not. This is Karma Yoga.
Through Karma Yoga, one continually reevaluats their understanding of the teachings with each new stage of progress—new information, new insights, and more personal experience. It is a journey. The faint of heart will disagree with me on this understanding of faith and opt for a kind of faith that requires less of them.
