"The basic assumption in our work is to prepare in the best possible fashion, so that we may stand quietly on the day of judgment, when it comes, in the knowledge that we did everything we could in the time that we had."
Lieutenant Colonel Jonathan Netanyahu (killed in action, Entebbe, July 4, 1976)
Although this quote is in reference to the short time in which Yoni & Sayeret Matkal had to prepare for Operation Thunderbolt (a mere 48 hrs), I find it to be very meaningful for the upcoming two days of the Jewish calendar (Yom Kippur beings at sundown on October 1st). "Our work" to me is our life, and during our life, we "prepare in the best possible fashion" to make the most of our life; Be it by strengthening the family ties, or by developing lasting friendships, or by going to university to set up our future, or by following our dreams to appease our hearts, or by following our religion in order to find our spiritual fulfillment. We do all of the above to prepare for the current, and for the future.
And so every year, we "stand quietly on the day of judgment" as Yom Kippur approaches. All that we have done passes by Hashem while we deprive our bodies of food & water. We pray and silently ask for forgiveness, hoping Hashem passes a positive judgment & stamps our name in the Book of Life for one more year. In this short period of 25 hrs, our prayers (of the day & the past year) hopefully signal to Hashem that "we did everything we could in the time that we had" to warrant that place for next year.
On that note, Gmar Chatima Tova to you all. May you and your loved ones be inscribed in the Book of Life for years to come, and may Israel be blessed with many years of peace and prosperity.
