I have done that, and successfully. See below. I'm quite confident that I am in continual contact with the highest power, which I continually consult for guidance.
Let me tell you about my "God," or better yet, since this guy has already done so quite eloquently, let me quote him. The following was written by a man named Richard Banford. He uses the word God metaphorically while telling you about what he respects. He is not talking about a sentient universe creator, but rather, what he (and I) respect more than faith in gods: reason. The faithful tend to convert all of that to their language anyway, so I'll do that as well. Feel free to consider secular humanism my religion, respect for reason worship, and reason a God that should be consulted and that can give reliable guidance the way that the faithful view their God and scriptures.
So, by that reckoning, I have already found the most rational "religion" and the highest power - reason. I have already called upon my "God" (reason) to intervene, and it led me to agnostic atheism and secular humanism.
"Do you know his name? Sure you do. He talks to you every day. You could not live a normal life without him. You believe in him, whether you like it or not. Unless you abandon him completely, you cannot deny he exists.
"My god is a more personal god than yours can ever be, for if you have enough sense to understand these words, my god lives within you. He lives within us all, to some degree. A heartbreaking few cannot understand him, but this is not their fault. The real tragedy is the multitudes who ignore much of his counsel, particularly when he questions your god too deeply.
"My god has been around longer than your god. He was here before the many other gods that preceded your god. Though you will likely scoff at the notion, my god was the father of your god, as he was to all gods. But that was long ago when he was young and not yet sure of himself. Though many of your god's followers try to hold him down, my god grows stronger and more independent each day.
"When your god expelled us from paradise for eating an apple, my god taught us to grow our own fruit.
"When your god forbade knowledge, demanding we live in ignorance, my god created books.
"When your god smote cities like a tantrum-prone child, my god helped to rebuild them.
"When your god insisted the world was flat, my god showed his followers it was round, to their peril at the hands of your god's followers.
"While your god watched in silence as children sickened and died, my god created medicines to make them well.
"When your god winked and nodded at slavery, my god argued passionately against it.
"While your god represses half the human race, my god considers woman to be the equal of man.
"When your god only helps those who help themselves, my god rolls up his sleeves and actually does help until your god decides to join in, and then steals all the credit.
"When your god inspired great buildings and great art, my god made them possible.
"While your god says we are all born sinners, tainted before we even draw breath, my god says we are all born innocent; a clean slate with limitless potential.
"While your god offers dubious allusions of an afterlife, my god provides for us here in this life.
"While your god makes amazing promises, but offers not a shred of proof, my god performs amazing deeds, and the proof is there to be seen by all.
"While your god demands blind faith and obsequious obedience, my god encourages questions, even about himself.
"When your god says "Thou shalt not," my god says "You can do anything."
"My god is reason. He does more in a day than your god will ever do."
I would recommend my "God" and "religion" (see the
Affirmations of Humanism for a summary) to you in place of what you have now, and make the same kind of plea to you to just give it a chance, to seek genuine wisdom using newly enlightened eyes, but we both know that that is no more an option for you than my following in your footsteps of faith and theism is for me.
