ORP: PKD & Psychosis description of sin

In "Martian Time Slip" by Philip K. Dick, the protagonist contemplates and in this passage we have, [:

Now I can see what psychosis is: the utter alienation of perception from the objects of the outside world, especially the objects which matter: the warmhearted people there.

And what takes their place?

A dreadful preoccupation with--the endless ebb and flow of one's own self.

The changes emanating from within which affect only the inside world.

It is a splitting apart of the two worlds, inner and outer, so that neither registers on the other.

Both exist, but each goes its own way.

It is the stopping of time. The end of experience, of anything new. Once the person becomes psychotic, nothing ever happens to him again.

This describes the progress of sin as alienation symptomatic of relations within humanity which ultimately progresses to the most consequential broken relationship--eternal separation from God.
