There is a very basic question one can ask about Olam Haba – the World to Come. It is our reward for being Jews, and as such, central to Jewish life. But if it so important, why doesn’t the Torah mention or discuss it anywhere?
The Maharal explains that the question is flawed. To promise something that is not empirically true or provable is cheap, and moreover, useless. The Rosh says that הרוצה לשקר ירחיק עדותו – about one who wants to lie, distance his testimony. We could be promised 72 golden cows, or similar, but the promise is essentially worthless, in the same way that a pop-up or scratch card assure you have won a billion dollars.
Hashem doesn’t have a problem telling us to keep the Shemittah, the Sabbatical year. It comes with a guarantee that for the farmers who keep it faithfully, the sixth year will yield a triple harvest – וְצִוִּיתִי אֶת בִּרְכָתִי לָכֶם בַּשָּׁנָה הַשִּׁשִּׁית וְעָשָׂת אֶת הַתְּבוּאָה לִשְׁלֹשׁ הַשָּׁנִים – I will command My blessing for you in the sixth year, and it will yield produce for three years. (25:21). There are countless stories even in recent years of farmers who have miraculously experienced a triple yield in spite of difficulties, such as drought, crop failure or insects plaguing neighboring fields. This is the strength of Torah.
It is no weakness in Judaism to not discuss Olam Haba. It is the strength of Torah to tell us about what is relevant in our lives, which Olam Haba is not.
