Translation of "Certainty" in Japanese

The nature and appeal of absolutes is that they provide certainty

教会原理の性質と魅力は 不確かな世界に

Very rarely is it possible to prove or predict something with certainty,

何かを確実に証明したり 予知できることはめったにないけれど

By the way, this week - no matter what flags are set - it's a certainty that there will be no ecchi scenes. You'll just have to bear with it a while.

ちなみにここ一週間は、例えばフラグが立っていようとも、Ｈシーンが無い事は確定事項だからな。暫くの間、辛抱な！
