Our Shabbos is also Yom Kippur,when Moshe finally gained atonement for us and came back on this 10th of Tishrei with the Second Luchos.This day for all time is a day where as it says in the Torah,'Yechaper Aleichem Le Taher Etchem Mikol Chatoteichem Lifnei HaShem Tit'haru,'-'For on this Day ,He (HaShem) shall provide atonement for you to cleanse you from all your sins before HaShem shall you be cleansed.'
We see that in this verse,atonement allows for 'Tahor,' - 'Cleansing.' So HaShem does not expect us to be angels who don't do wrong.Yiddishkeit allows for the truth that a person can be righteous and perfect before HaShem even though they have made mistakes.G-D,in His infinite mercy,understands how strong is the Yetzer Horah and allows us to come before Him and really be sorry for what we have done.This is truly how HaShem wants it to be.
The word 'Kaper,' means "Atone or Forgiveness,' so HaShem did create such a concept incase we sin.HaShem knows we are human and thus fallible.The very fact of realizing that we are wrong,is enough to stir HaShem's Mercy and allow us closer to HaShem.This is one of the most beautiful concepts HaShem made for us,as it shows how deeply compassionate and self-less is HaShem,to put aside His own pain when we hurt Him and think about us.How much more so,should we do the same thing for our fellow people.This is not a time for anger.This is not a time for selfish resentment.This is a time to truly forgive ,for we too are human and the same path people walk with us hoping we will forgive them,we too need to walk,hoping G-D will forgive us. 
This is a time to put our own needs aside for others.This is a time to be open hearted to the needs of others being kind and loving and forgiving.Let those family grudges go.Let that anger go.Let upsets go and be free,for there is no freer person,than one who forgives.
Yom HaKippurim as it is called in the Torah suggests 'plural' forgiveness which can show us that there are many sins that we have done-those we know of and so many we don't know of.None of us have attained perfection.We are all working toward it.Never think that we are fine and have nothing to atone for as there are so many things we have done without even realizing it.Torah says,'Mikol Chatoteichem,'-'From ALL YOUR SINS.' Showing us this includes ALL of us and that there are MANY SINS that we ALL commit that needs atoning.
So may we use this special time totally for coming right with HaShem and with others.Let us remember,as the verse says,that we stand 'Lifnei HaShem,' - 'Before HaShem ' which is such an awesome thought to behold.So let us remember before Whom we stand and totally give ourselves to G-D.May we all attain atonement and work toward bringing ourselves to not repeating past aveiras and coming closer with HaShem.
Let this also be a time to come close to G-D and leave that which HaShem has not commanded,alone.This Yom Kippur,may all,open themselves up to following a Torah way of life and not be taken by other things,no matter how real they may look.G-D gave us a guide to follow to return to Him.Let all come,on this Holy Day of Shabbos and Yom Kippur to return to HaShem with love,and turn away from other beliefs that try filter in,showing themselves to be holy,but in reality,are a way away (Chas Ve Shalom) from HaShem.
As you stand before G-D , on this Holy Day of Shabbos and Yom Kippur, take the precious opportunity G-D is giving you and return to G-D and the way G-D Commands us to follow.Please return to G-D.
With utmost deepest love,I wish HaShem a Holy Shabbos Kodesh with Love and Shanah Tova and to all,a Holy Shabbos Kodesh with love and a Tzom Kal and G'mar Chasima Tova.May you all be sealed for good.Have a sweet Shabbos.
