People are scared and I don't blame them.

[Angrboda]

And what if that link with the unseen is not a link to God, but just a link to unseen natural processes?  It being unseen means you can't be sure. 

That depends on how you understand the word unseen.  God is both hidden and manifest, we are both hidden and manifest. We are both manifestly there and we are unseen. In fact we are manifestly unseen. That is it's obvious we are unseen. 

What is the manifest aspect of God?
