HaShomer Shabbos Meichalilo-Al Tikri Meichalilo Ella Machul Lo

Last week I mentioned a chiddush from the Chovos HaLevovos in Hilchos Teshuva that I saw brought down by the Sidduro Shel Shabbos. The basic idea is that even if it is not in a person's power to do a complete teshuva, HKBH will soemtimes help you out. The Sidduro Shel Shabbos uses this idea to explain the gemara in Shabbos 118B. The gemara quotes the possuk in Yeshaya (56:2) "'hashomer shabbos meichalilo'-al tikri meichalilo ella machul lo". The meaning of the gemara is that Shabbos has the koach to have a person's aveiros forgiven. The Sidduro Shel Shabbos explains that we are talking about someone who prepares himself before Shabbos and does teshuva before Shabbos (This is the geder of "one who prepares Erev Shabbos will eat on Shabbos). However, even if someone does teshuva, there are certain aveiros that don't have a kapparah until Yom Kippur, so how can it be that Shabbos alone can cause your aveiros to be forgiven? He answers that this is where the idea of the Chovos HaLevovos comes in. As long as you do everything in your power, thru the koach of Shabbis, HKBH will forgive you for all your aveiros.

The question remains what happens after Shabbos? So if you are able to refrian from other aveiros then you will be able to tain the kedusha of Shabbos and your aveiros will be forgiven. Otherwise, when you go back to doing aveiros the kedusha of Shabbos will leave and the ramifications of your previous aveiros will come back. The kitrug of ones aveiros are onlyheld in check kol z'man you have the kedusha of Shabbos. Once the kedusha of Shabbos leaves the kitrug comes back.

This is also the idea of the ma'amar chazal that Moshiach will come when we keep two Shabbosim. The idea is that the first 3 days after Shabbos are tied to the previous Shabbos. The last 3 days of teh week are tied to the following Shabbos. If you refrian from aveiros the whole week, then the kedusha of the previous Shabbos joins with the kedusha of the following Shabbos to create one long week of kedusha. This week of kedusha is strong enough to be mesakein the cheit of Adam who created a p'gam in the 6 days of the week and this kedusha can bring Moshiach.
