It states (Devarim 29:9) לפני כולכם היום נצבים אתם אלקיכם 'ה, "You are all standing this day before Hashem, your G-d." Notice that Moshe said אתם, you are standing before Hashem. These words imply that the nation was standing before Hashem, but Moshe himself wasn't. The Sfas Emes explains that Moshe Rabbeinu was saying to Bnei Yisrael, "You are on a higher level than I am. You are before Hashem, but I can't be so close to Hashem.
As Chazal say, 'In the place where baalei teshuvah stand, the greatest tzaddikim cannot stand. You are at a level beyond where I can be.'"
The Sfas Emes concludes that this is an encouraging lesson for our generation. We are a lowly generation, which is to our benefit, because when we do teshuvah, we reach the highest levels.
It states (Devarim 30:5) מאבתיך והרבך והיטבך, "He will do good to you, and He will make you more numerous than your forefathers." The Chasam Sofer z'tl wonderfully explains that Hashem made us greater than the Avos hakadoshim because we are baalei teshuvah, and baalei teshuvah reach levels that the greatest tzaddikim cannot.
A counsel for teshuvah is to accept a kabbalah tovah. Slonimer tzaddikim say that a good kabbalah is a protection in this world and the next world, but it must be kept continuously.
