Yeah, no evidence to prove him yet no evidence to disprove him either.
"Live by faith and not by sight"
I live by faith you live by sight.
Limiting God to "Human understanding" is like limiting him in to human form. If you think you fully understood God and his teachings, well, your wrong.
I doesnt matter if he cant be proven, It doesnt matter if people mock God. All I know is that I have faith, believe that he existed and im content. Ive seen God change people's lives, turn them around to the right direction. As long as believing in him and sharing that belief can change peple's lives. Im happy with that too.
Hope you understand.
"yet no evidence to disprove him either"
The burden of proof rests on the person making the positive claim. "There is a God" would be the positive claim here and therefore the burden of proof is on you. If I told you there is a flying pink unicorn living on mars it would be up to me to prove it, not up to you to disprove it. If I said "well you can't disprove it!" would you then believe there is a flying pink unicorn living on mars?
By the way, I've never met a non-believer who believes there is defintely no God, we just a lack a belief in one due to lack of evidence, due to lack of any reason to believe there is one, and until given a reason the default position is disbelief.
"I live by faith"
Firstly, how exactly is this desirable?
Secondly, I don't think you do. I think you apply reason and the need of evidence to most things in life, e.g. if somebody were to tell you they were abducted by aliens, you wouldn't have faith that this was true (presumably) but instead would ask for some evidence, a logical reason to believe his claim, but you make an acception for this idea of a God.
