You won’t understand every chapter while you’re in it. You can trust the Author anyway.

Meaning usually arrives after the fact. In the middle of a difficult stretch you have no access to how it fits, because the parts that would explain it have not happened yet, and demanding coherence now is asking for something the moment cannot give. Trust here is placed in the one arranging the story rather than in your ability to read it.

Stop forcing an interpretation onto what you are living through. Keep a record instead, plainly, of what is happening. Reread it later, when the shape is available and the meaning can be seen rather than manufactured.
