> I'm not sure how feeling more confident about something you can't verify makes it more than a belief.
You know that when it comes right down to it, you can't even prove to me that you exist. Of course we all accept such things, but you really can't verify it. Formulating foolproof criteria for certainty and knowledge has never been successful.
I also came across an interesting article (
https://www.pbs.org/wgbh/nova/article/falsifiability/) that even science functions under a false illusion of verifiability. But, of course, we still accept such things as reality and knowledge. We still know that things are true even though absolute verification may be out of reach.
> Is there only one truth?
Truth is both broad and narrow. There are truths everywhere. Every book I read has truth in it. Every discipline has truth in it. Even every religion has truth somewhere in it. We are surrounded by true things.
On the other hand, truth is very narrow. There may be 100 theories about what happened to Amelia Earhart, but once we discover the truth (if we ever do), only 1 of them (if that) will be right.
I know from researching the topic that there are more than a dozen hypotheses about where Solomon's Temple stood on the temple mount in Jerusalem and which direction it faced. But only 1 of them is true.
When it comes to God, I've considered the logic of the theistic position. I've examined the science to infer the most reasonable conclusion about the nature of the universe, its source and characteristics. I've examined the evidences about the historicity of the Bible. Considering all the angles and evidence, I've become convinced beyond a shadow of a doubt, let alone just a reasonable doubt, that God exists. I would be remiss not to pass that on.
> How would the promise of deceased loved ones in heaven compare to the dangers of walking on the road?
They compare favorably. They are both true. In the realm of science we make flat statements that we
know the world exists, yet we have to
believe God exists. Why should we use different wording? It has to do with a principle of authority. Our view of science causes us to talk talk about material things as existent, but non-material things as simply our opinions or beliefs. And yet a moral law within us (some sense of right and wrong) exists just as surely as the stars in the heavens (reflecting with Kant). Does dark matter exist? The theory says yes, but it is unknown what kind of materiality it has. So do we know it exists or do we believe it exists?
And what about time? It's non-material, yet no one questions its existence. We don't just have to "believe" in it. We know that time is relative to us while being independent from us. Present, past and future do not exist in physics; they exist in our experience only in relation to us.
The principles of Physics are delimited for the sake of objectivity, but physics cannot and does not cover the whole of reality. Metaphysics have always existed alongside of Physics and are needed to fill in the totality of reality. Never in history were these things seen as in opposition. Humans always seek to give sense and value to their life. Belief and knowledge together make up the totality of reality; science cannot have ultimate authority because it is only one slice of reality.
Knowing God exists is no different than knowing my car mechanic exists. You might object to this right off the bat, but think about it. Suppose someone says their friend went to Europe on a vacation, but he promises to call when he returns. It would be absurd to claim because I can't see him and touch him that I can't be sure he exists. The Bible also tells us of a God who has been here tangibly in the past (Jesus), has told us about himself, who has gone away and has promised to return.
Have you ever seen one of those Magic Eye pictures? (You look at it sort of cross-eyed, or 10' beyond it, and then the picture comes into clarity.) We have to learn how to see a coherent pattern. We process clues, we learn how and where to focus, and we can make something out of it.
Knowing God, knowing my mechanic, or seeing the picture: we're just learning to evaluate data to derive a coherent pattern of reason.
