Shabbos, A Gift of Time?

VAYAKHEL - PEKUDEIShabbos, A Gift of Time? Notice how all the recent event happened on Shabbos, why then? What is so unique about the Shabbos?Why does Moshe preface the laws of Shabbos, before telling the Jews about the construction of Tabernacle? Especially that when G-d instructed him about the Tabernacle, it was only afterwards, that he was told about the laws of shabbos?As we will come to learn Shabbos is more then a set of restrictions. Shabbos is a time where we can experience the world to come in the present. Shabbos is a gift of time, and a prerequisite to making G-d's home.
