Repentance is the key. If we truly repent G-d will save us. Korach’s two sons were two of key leaders in the rebellion against Moshe yet they repent in their hearts and were spared death.
I too have done some horrible things in my life. When I cried out to G-d and repented of my evils ways and turned back to G-d he forgave me and saved my life.
Yeshua is the L-rd of my life.
Korach’s sons did not die [in their father’s mutiny]. Numbers 26:11
The Rebbe explains: The sons of Korach played a key role in his rebellion, and were therefore swallowed up into the ground along with the other rebels. However, since Korach’s sons – unlike the others – repented in their hearts, they were spared the death penalty: G‑d allowed them to stay alive in an underground cave until the rest of their generation died out, after which He allowed them to emerge from hiding and resume their lives in the community. Had they acted upon their regret, they would have been spared even this lesser punishment. Their survival shows us the tremendous power of repentance – even when it is not acted upon as it should be.
This insight should quiet any doubts that we may have about the possibility of redemption in our times. Even merely thinking about repenting is sufficient to bring about the final Redemption – especially when this is added to the merits we have accrued throughout our long exile: the Torah we have studied, the commandments we have performed, and the martyrdom we have suffered.1
