But how can you verify claims about God by asking God? Isn't that affirming the consequent? You're already assuming the truth of the claims.
Yes, that is how you always establish the truth of something. You first make an assumption one way or the other. This is called the null hypothesis. You then determine what you would expect to observe if that something was true. You then run the test to see if you get the result you expected.
From my personal first hand experiences and the second hand experiences of those I know, I have decided to take God's existence as the null hypothesis. Do you have a problem with that?
1) How do you verify God's existence?
2) How do you verify that what God is supposedly communicating to you is accurate?
Personally I expect an experience that will be impactful and unique. It cannot be something I have experienced before. There experience needs to remove all feelings of doubt and anxiety. The fruits of the spirit (according to Christianity) are "love, joy, peace, longsuffering, gentleness, goodness, faith,". If the God of Christianity is true, then I expect these elements to attend his manifestation.
But there are many who do assert that there is no God. Why do you discount their experiences?
What are their experiences. Who has experienced the non-existence of God? Secondly I do not discount anyone's experience. But I am just one person. I can only deal with one thing at a time.
And of all of those people, how many of them have presented actual evidence to support their claims?
Their lives were the evidence. And that is the evidence I expect to give to the World when I have found God. "By this shall all men know that ye are my disciples, if ye have love one for another".
You cannot be said to be investigating their claims honestly if you have a bias towards assuming their claims as being true.
I could likewise say few atheists can claim to be investigating the claim that there is a God since most are biased towards the idea that he doesn't exist. In fact I could extend it and say that anyone who lives and loves to live a life that is contrary to the teachings of the Christian God cannot honestly investigate his existence since they will likely have a clear bias towards his non-existence.
