The Torah uses a unique expression - for 6 days work will be done & the Shabos is holy a day of total rest all who doing certain forms of work are to be put to death.
Work will be done - is explained because Hashem runs the world. We have to realize that it is all up to Him. We need to do some efforts with the realization that we cannot accomplish anything without His constant input. Now may be a good time for a gem of Torah study. www.GemsofTorah.com
