Blessed and Sanctified
Hashem blessed Shabbos by providing a double portion of manna on Friday so that the Jews would not need to collect it on Shabbos. He sanctified Shabbos, making it special and Holy, by refraining from providing the manna on that day.
This is a model for how we are to relate to our livelihood on Shabbos. Hashem provides for all of our needs. He takes care of us during the week, as well as on Shabbos. G-d relieves us of the burden of having to work on Shabbos. If a person insists on working on Shabbos, he will add to the amount of effort he puts in, but not to the amount of income he will receive.
We can choose to use Shabbos as a day to connect and appreciate the blessings that Hashem gives us. We can choose to be His partner in sanctifying the day as unique and holy. What a beautiful way to testify our belief and trust that Hashem is indeed the Creator of the Universe.
