That’s a rich thing to sit with. There’s a real tradition behind this — many contemplative paths treat uncertainty not as a problem to fix but as the actual terrain where reverence grows. Certainty can flatten awe; you know the shape of things, so you stop looking. Uncertainty keeps you looking.

A few threads worth pulling on, if you want to explore this seriously rather than resolve it into a neat technique:

Why uncertainty and fear-of-God might actually be connected, not opposed

If “fear of the Creator” means something like awe, trembling reverence, a sense of being small before something vast and other — then certainty is often the enemy of that feeling, not its foundation. Once you think you’ve got God figured out — His plans, His reasons, the shape of the whole picture — you’ve quietly made Him manageable. Uncertainty, held honestly, keeps the scale right. You’re not in control of the outcome, not fully able to trace the reasons, not able to resolve the mystery on demand. That’s uncomfortable. It’s also, arguably, closer to the truth of the relationship than false clarity would be.

The temptation to resolve too quickly

The instinct to resolve uncertainty fast usually isn’t really about truth-seeking — it’s about anxiety management. Not-knowing feels unbearable, so the mind reaches for any explanation, even a bad one, just to stop the discomfort. If you actually sit with it instead, you often notice: the urge to resolve is a body sensation as much as a thought. Naming that (“this is my mind trying to escape the discomfort, not trying to find truth”) can let you stay in the question longer without forcing an answer.

What “sitting with it” could look like practically

When a hard question comes up (why suffering, why silence, why this outcome), resist finishing the sentence with an answer. Let the question stand unanswered for a while — in prayer, in journaling, in silence — rather than reaching for the first available resolution.
Notice the difference between humility before mystery and anxious spinning. The first has a kind of stillness in it even though nothing is resolved. The second is just discomfort in disguise. Sitting with uncertainty aims at the first.
Some traditions frame this explicitly — not-knowing as itself a posture of reverence, since claiming full comprehension of the Creator would be a kind of small-mindedness about something infinite.

A caution

There’s a difference between uncertainty that expands awe and uncertainty that curdles into dread or despair. If this practice starts feeling like anxious rumination rather than reverent stillness, that’s worth noticing — the goal (as you’ve framed it) is fear in the reverential sense, not fear as suffering for its own sake.

What tradition or framework are you approaching this from, if any — that’ll shape what “sitting with it” should actually look like in practice.
