This is the thought we have as we go into Ne’ilah - the concluding service of the holiest day of the year, Yom Kippur. We realize that this is the last moment we have before the gates of Heaven revert to their year round status with respect to Teshuva.
We can of course always do Teshuva for any and all transgressions. But for the ten days beginning with Rosh Hashanna and culminating with Yom Kippur we are given a special opportunity to repent of our sins. God is more open (as it were) to Teshuva then. So we pray hard at this time of year so that our Teshuva is accepted. Yom Kippur is the last chance to rescind any Heavenly negative decrees on Rosh Hashanna. By the end of the day our fate is sealed.
May God grant all of Klal Yisroel a sweet year. A year of good health and happiness. No more pain! No more sickness - physical or mental.
So should it be written. So should it be sealed.
Have an easy and successful fast.
