Throughout the centuries, various religions have come up with various prescriptions that were designed specifically to be a response to God's will for mankind, and for the spiritual healing of mankind as it's reward. These prescriptions tend to be direct reflections of the image of God the various religions profess and promote, and the promised results tend to exemplify an idealization of mankind's proper condition in "God's eyes".
I don't completely disagree with this. I think that primitive cultures tended to see their misfortunes in terms of punishment from a god and their good fortunes in terms of help or advocacy from a god. This is certainly true of the Gilgamesh epic, in which Enlil caused the global flood that nearly destroyed mankind (leading to Uta-Napishti's construction of the ark) and Enki advocated for the human race in the face of Enlil's anger against us. In modern cosmology, the dominant God is an advocate for humanity, and Satan, demoted to a kind of super-demon, causes evil in the world.
It's important to understand that these kinds of prescriptions are the direct result of a specific God-concept, being acted upon as one believes God wishes, in hopes of achieving the results that God has promised, and which mankind rightfully deserves.
Well, my interpretation of all of this is that God is human-besotted precisely because he is a figment of human imagination. Hence, his morality tends to be informed by humanistic principles--those that we intuitively feel benefit our species in general.
A classic example of such a prescription might look something like this:
1. To pray for humility.
2. To reflect upon one's "sins".
3. To confess these sins to a priest or minister.
4. To make some act of contrition or restitution for the damage these sins have done to others.
5. Repeat previous steps for all future "sins".
This kind of reasoning is predicated on the belief that our misfortunes derive from the anger of a god. We can somehow appease that god by praising him/her and making sacrifices to show our devotion. That will lead to an improvement in our circumstances in the future. At a minimum, it guarantees triumph over human mortality. That was the basic theme of the Bilgames/Gilgamesh epic, which preceded the Abrahamic scripture by perhaps a millennium.
This and similar prescriptions have been practiced over the centuries by countless humans beings from various religious traditions and ideologies, and most found that through this prescription they achieved pretty much exactly what was promised. It's a simple but effective way of learning to alter one's own behavior in favor of an ideal based on the concept of "God".
I think that you miss something vitally important here. Human beings are notoriously susceptible to the technique of cold reading, where people ignore missed guesses and predictions in favor of the relatively few positive ones. We tend to cherry-pick what we want to believe in. So the one time that a rain dance precedes a deluge, people leap to the wild conclusion of causal effect, when, in fact, it was just normal serendipity.
A concept of God, when acted upon according to that idea, produces the results that the idea itself promises. I believe this is evidence in the same way any other idea is ratified by testing it through action.
The fact that we are predisposed to believe what we want to believe is a problem for your position. It took humanity many millennia of trial and error to discover the scientific method, which serves as an antidote to flawed reliance on supernatural explanations for phenomena that we cannot immediately explain in terms of naturally understood physical laws.
A similar idea might be something like: Carol claims she loves Bill, and wants to marry Bill and live with Bill as his wife. But BIll is skeptical, so he proposes that they live together unmarried for a time, to see how it goes. But as they live together, Bill discovers that Carol does not behave as a woman who loves her husband, but as a woman who wants to possess him, and control him, and punish him when he does not oblige her needs. She says she loves him, and wants to be his wife, but she doesn't act as if she loves him, nor does she treat him like a husband. Bill was presented with an idea. And he wanted to find out if that idea had correspondence in reality (the measure of truth). So he lived as if the idea was "real" for whatever length of time it took for him to satisfy himself that it either was or was not actually true. In this case, Bill discovered that the idea was false. It did not have correspondence in actuality.
Yet there are many men who come to feel alienated from their wives because they misperceived their behavior and held unrealistic expectations about them. As you grow older, you learn that people are a lot more complex than they seemed during your youth. It is not usually the case that one person is wrong and the other right in such situations.
The religious prescription I posted, above, has been tried and tested by millions of human beings, throughout centuries, and found to work for them as claimed.
It has also been found to fail. But, if we ignore the failures, then it seems like a huge success.
