When a person wakes up every morning, he gets to thank Hashem for giving him another day to be on this world. In this week's parsha, we read about the final days of Sara's life. Sara was the mother of the religious world so therefore it was a sad for the Jewish people when she suddenly passed away.
A lesson we could take from this is to be grateful for the days we have. Unfortunately sometimes people don't get the ability to continue on this world, but just know that they want us to continue the good!
All the best
