See, I'm beginning to understand some of my own issues.
So much of being a believer seems to obfuscate logic and accountability. And I'm more of an empirical sort of dude.
Where did God come from? He's always been.
Does God answer prayers? He does, but it may not be in the way you imagine.
How are children sinners? They were born with original sin.
I mean, if I were looking to excuse a daydream, this would be the type of responses I'd give. Nothing can be measured, nothing can be shown, and something may happen, or not. We start with a debt (of some kind), no matter our circumstance.
It's all so nebulous. Which is where Blind Faith comes in. However, blind faith, as is often stated, is what you need when you lack evidence. Blind Faith suggests you should believe, even though there is no worldly (scientific) reason to do so.
This is the barrier I have. My brain doesn't work that way. I can't accept something beyond the universe we live in, beyond the processes and interactions we know (which is not to say we know everything about everything, because the universe is a VERY big place). I cannot accept that a new born, right from the womb, has sin.
We also know that psychological humans can find a great inner strength. We can fight through impossible odds. Some of the results of which appear to be attributed to a God.
Let alone all the different Gods. I saw a figure of 18,000 Gods or animals have, at one time or another, been worshiped by man. And Christianity spread, partly, by way of imperialism. And that the belief one has is connected to where you happen to be born (if you're born in India, you're more likely to be Hindu).
But much is obscured by the use religion is put. Can you really be a Christian that advocates for the death of the people of other nations (with other beliefs?)
Or how forgiveness is abused to make heinous acts legitimate.
I guess what I'm saying here is - belief isn't simply about a belief in a God, the question is far more complex.
