Translation of "Arising" in Japanese

I'm afraid of discord arising with my husband so I'm turning a blind eye to his mistress.

夫との間に波風が立つのが恐くて、愛人の存在は知らない振りをしています。

Opportunities of time vouchsafed by Heaven are not equal to advantages of situation afforded by the Earth, and advantages of situation afforded by the Earth are not equal to the union arising from the accord of Men.

天の時は地の利に如かず、地の利は人の和に如かず。
