Why religion fails

I think I have identified partially why religion fails for so many people.
I will try to get the whole train of thought in. Hopefully by the time I get to the end, it will make sense.

The ideal goal of religion is to bring people to awareness of the Creator.
Religion is not the equivalent of spiritual truth.
Religion is composed of a group of people who engage in certain patterns of behavior and speech.
The patterns of religious doctrines and practices are like a path that has the capacity to lead us to the Creator.
But it is the Creator who directly teaches us spiritual truth.
Spiritual truth can not be received, communicated, or comprehended in any other way, except by the Creator.
People may find the social and organizational aspect of religion to be detrimental or beneficial.
They may find the words spoken in religion to be beautiful or reprehensible.
This dissonance is the result of humans trying to reflect God and spiritual truth through their own humanity.
Religion fails because humans fail. They fail to obtain. Often even if they have obtained, they fail to reflect adequately. Humanity gets in the way.
Consequently many never succeed in the opportunity to be taught directly by the Creator so that they may come to know spiritual truth.

When this happens, religion fails. It becomes nothing more than a social gathering of humans who in their humanity are full of intolerance, prejudices, bias, tradition, and social norms. The best aspects of this state reflects only the best aspects of their humanity and the worst is apparent when people are persecuted and sometimes even killed in the name of "religion". This is not unique to religion-- rather, it is general to humanity.
