In other words, you can't demonstrate this truth, you simply say, this is what you believe?
This is the basis of
all religions. Hence the need in the early days to provide "proof". A local flood, eruption, disease, plagues, drought, wind, sun, rain, are the gods powers. In a modern world we know that's not true. So their truth is left with things that can't prove.
Jesus made it very clear about the power of prayer, never comes true. Some believe they can talk to god. God never tells them something they didn't already know.
"
I just really like to pray. It is comforting to know because I choose to have faith I can have the Almighty to talk to and have a relationship with." Can you prove you're not just talking it over with yourself? Talking things over with myself is good for me, and it did help me rationalise what a bastard that priest was. Now I've discovered his church is full of similar bastards and the hierarchy did their bast to hide them. By moving them to parishes to offend again. How does prayer settle that fact in my head, better then suing the church into poverty?
As I grew up and watched more on the actions of organised religions, I affirmed my belief that the concept was flawed from the start. Because it was men writing what men wanted. Now the evidence is clear that's true.
The question of if there is or isn't a god is irrelevant. The question is, is it the god that ordered donations of money, campaigning, murder, rape, execution, war, etc. Or the one that wouldn't ever do those things?
Try finding an organised church that didn't sit aside a despotic leader telling the people god's will, was also the will of the leader.
