Writing is a way to live your questions meaningfully.
Write in order to know what you think . Words provide the conceptual scaffoldings on which your ideas can grow.
You don’t always have to be certain to write, just like you don’t always need to be certain to have faith. Struggle is necessary for both to grow. The objective of your writing (and your faith) is far more important than your steadiness in getting there.
It is possible to understand without knowing.
