עָתִיד הַקָּדוֹשׁ בָּרוּךְ הוּא לַעֲשׂוֹת מָחוֹל לַצַּדִּיקִים, וְהוּא יוֹשֵׁב בֵּינֵיהֶם בְּגַן עֵדֶן; וְכָל אֶחָד וְאֶחָד מַרְאֶה בְּאֶצְבָּעוֹ זֶה ה' קִוִּינוּ לוֹ, הִנֵּה אֶלֺקֵינוּ זֶה; קִוִּנוּ לוֹ וְיוֹשִׁיעֵנוּ
Usid Hakadosh Baruch Hu la'asos machol la'tzaddikim, ve'hu yosheiv bei'neihem b'gan eden; ve'chol echad ve'echad mar'eh be'etzba'o "ze Hashem kivinu lo, hinei Elokeinu ze; kivinu lo ve'yoshi'einu."
"In the future the Holy One, Blessed is He, will make a circle of all the righteous people, and He will sit among them in Gan Eden; and each and every one will point with his finger (and say), 'This is Hashem to Whom we hoped; Behold! This is our G-d; we hoped to Him and He saved us'." (Taanis 31a- the song changes the order of the words a bit)
The word "מָחוֹל" has the same root letters as the word "מחל", forgive. The Gemara implies that in the future G-d will forgive all the sins of Bnei Yisrael, and that all of us will be privileged to join this circle. As it says in Yeshayahu (60:21): "...וְעַמֵךְ כֻּלָם צַדִיקִים" "And Your people are all righteous..." (Hagahos Yaavetz).
Hashem is our father. Just as a father always forgives and never abandons his children, al achas kama va'kama (how much more so) the same is true by Hakadosh Baruch Hu.
