Yet, another explanation for why the meraglim sinned is that they lost sight of Hashem's abilities. According to what they understood, there was no way they could win the war against the thirty-one nations living in Eretz Canaan. They forgot that Hashem has ways that are hidden.
The Rebbe of Piaceszna zt’l, in the Warsaw ghetto, taught, “A Yid must believe in Hashem’s salvation, not only when he understands how it can happen. Even if he has no plan and doesn’t see any possibility, he still believes and trusts in Hashem's salvation.
“During these times [the Holocaust], it is probably better that one doesn’t seek rational solutions on how to save himself because he probably won’t find, and then he might fall from his emunah. And lacking emunah and bitachon may prevent the salvation from occurring, chas veshalom. Rather, one should say ‘Although...there doesn’t seem to be a solution... nevertheless, I believe Hashem will save me beyond the rules of nature.’”
He explains that this is what Kalev told the nation when he said (13:30), וירשנו נעלה עלה לה נוכל יכול כי אותה, “We will go up to Eretz Yisrael and we will inherit it. We are capable of doing so.” He said this to calm the nation when they were afraid to go to Eretz Canaan. But notice that Kalev didn't mention any strategy. He just said, "We are capable. We can conquer the land." How did that calm the nation? Essentially, he told them, "We don't have to know how we will succeed in this war; Hashem has His ways. We just have to trust in Him."
And this is a lesson in bitachon for all our needs. We don't always understand how we will cover debts, find shidduchim, and countless other struggles in life, but we don't have to know how. We can trust in Hashem because Hashem has ways to resolve all our problems.
Rashi writes that Kalev told the nation, “Even if it is in heaven and Moshe tells us to make ladders to go up there, we will succeed with whatever he says.” This sounds even more improbable. Who can climb a ladder up to the heavens?
The Rebbe of Piaceszna zt’l answers that Kalev said, “We can win the war against the giants. We can even climb up to the heavens if that's Hashem’s decree. If you ask me how that’s possible, I also don’t know. But we trust in Hashem and in Moshe, His servant. If Hashem tells us to conquer the land, we can do it.”
