The moment you start using faith as your base, you've made your first mistake.
Remember that if watchmakers have makers; their makers also have their own makers, ad infinitum. If you follow your logic to its conclusion, it is not logical to assume that a maker would not have his/her maker.
Some properties in nature are emergent. Maybe life is just that. A carbon-based, self-replicating dune.
It is not reasonable to believe in something without evidence.
God does not speak, God does not exist. If you hear God you are a delusional schizophrenic.
Oh, oh. You are constantly making your first mistake. And you know it by the mistakes you have made.
Just because you don't want to admit your mistakes, doesn't mean that you haven't made them. Did you ever get a problem wrong in school? Did you ever burn yourself? Did you ever get a little fender bender? What have you done wrong that you weren't expecting to be wrong, but it was wrong?
The point is that many of the things you did wrong, you thought you did right. Before you found out that you were wrong, you thought you were right. Some of them may have even come as a surprise. Some of them, after you were told that you were wrong, you still couldn't believe it, and had to work through it thoroughly before you realized that you were wrong.
Now, in the mistakes you made, you were honestly thinking that you didn't make a mistake until you found out later that you did. You had faith in your abilities, or in your surroundings, or in the integrity of others, or in whatever, that you were acting correctly. Then you found out there was a mistake involved.
Think of all the people who made a driving mistake, if only it was that they were in the wrong place at the wrong time. Think of all the airliner crashes where people died... died having faith in all the circumstances of the flight... but the plane crashed and killed them.
Now, think about anything that you do. How do you know that you aren't making a mistake this time? Sure, most of the things that you do work out. But how do you know for a fact that this one thing isn't a mistake? You don't! You don't know FOR A FACT about any of them until later. If you absolutely DID know, you wouldn't make your mistakes.
You are essentially acting in faith in all of it. Experience tells you that things generally run pretty smooth. But experience, also, tells you that you have and will make mistakes. But you don't just stop. You continue because you have faith that if their are mistakes in your life, that somehow you will be able to handle them.
If life happened to be a little less stable than it is, you would be making more mistakes. As it is, you have faith that it will work out.
Because, unlike you, I have read all three Abrahamic holy books, and there is no way in hell that these books were inspired by the creator of the universe.
And because the creator of the universe failed to show his sorry ass, i.e. there is absolutely no evidence of his existence.
Just people talking about their dreams, feelings, hopes, and delusions. That is all religions are, smoke and mirrors.
I hope that satisfies your curiosity.
