It's MY life.
MINE, MINE, MINE!
That is the visceral feeling many of us have. When someone dies people are shocked. "His" life was taken.
This is a mistake. It is life that belongs to Hashem that was given to us as a gift. A huuuuuuge, unearned, undeserved gift.
We actually say it every day - 3 times [4 if we forgot yaaleh vi-yavo...].
על חיינו המסורים בידיך - [Thank you Hashem] for our lives that are given over into your hands.
This morning I went to check up on my [almost] 2 year old Adina who was sleeping. She was breathing [THANK G-D!]. I was watching and marveling at her breathing. Then I thought "I could only watch my daughter get married [a different one - Adina'le is not quite ready] last week because he gave her MILLIONS of consecutive, uninterrupted breaths."
חסדי השם כי לא תמנו כי לא כלו רחמיו.
