I don't think this is blind. I think this is honest.
If a person hasn't seen god, talked to god, and sees suffering and an absence of god in the world, can they be blamed for concluding that god doesn't exist?
If someone insisted that their was a secret person leading the United States, and the person insists that evidence exists, even though no sign of, or communication exists, can a person be blamed for rejecting the idea that such a person doesn't exist?
What I am talking about isn't the possibility that god exists. I think this is a shallow attempt to establish that a "higher power" exists. To that I say, this is correct.
The problem gets sticky when various competing religious agendas try to claim the higher power as their own. Jehovah. Jesus. Allah. Any of them could clear this up by coming forward. But they haven't.
The biggest error I think with Christian theists in this manner of debate is simple. The fact that science cannot disprove a higher power doesn't mean that potentially, a higher power is the Jesus you believe in.
Why is it that if I allow for the existence of a higher power, that I must then in turn, believe that this higher power is the Jesus that you worship? What evidence or facts should jolt me in that direction?
Belief in higher powers are fine with me. But Jesus isn't insisting that I worship him. You are. Does that make sense?
