Faith: The belief in something regardless of evidence or lack thereof.
Look, I only have two options here. I can accept things based on whether they are supported by evidence, or I can accept anything I want to just by having faith. I can't pick and choose depending on the topic.
There is plenty of evidence, as I have already discussed.
Here's an example.
I believe in unicorns. You may not, but I have had personal experiences which convinced me that they must be real. There may not be obvious evidence of their existence, but they wouldn't be such beautiful, mythical creatures if they were obvious to everyone. I have faith that they exist. There is no proof that they don't exist either. You should look deep inside yourself and ask to accept unicorns into your life, because they will add so much meaning and value to your life.
Now, try to convince me that my faith is misplaced. It can't be done. An argument on faith is completely immune to all logic because it's completely illogical. And yet surely you agree any thinking person would dismiss the belief in unicorns as unfounded. Why? Well, think about that for a bit.
You just made that up as an example. I'm talking about a living faith, that is against man's nature to even keep, but one which a believer does inevitably keep through continuous revelation and communication with a living God, and wrestling with tough questions and answers.
What is the actual observable difference between having faith in God, having faith that unicorns exist, or having faith that there's an invisible pink teapot orbiting the Earth?
Jesus walked this earth, and there is historical evidence of this. There is no historical evidence of any of those other things.
Jesus claimed to be the son of God, those things didn't. He also happened to be telling the truth.
