When I began reading Sefer HaMitzvos a few days ago, I was at first taken aback by the fact that the mitzvos I were reading about were seemingly impractical. I read about plowing fields; the Sabbatical year and the jubilee year- hardly things which I would use in day to day life. I wanted mitzvos I could use and learn from. And it was only this morning that I realised that I could in fact learn from them- and that I must.
G-d can foresee the future as easily as He can remember the past. Surely, he knew that we would be reading Sefer HaMitzvos in the 21st century when these laws seemed irrelevant. He knew when He gave us these laws that we would one day see them as obsolete. And that’s a part of the reason, I believe, why we must study them. By studying laws which we see no immediate purpose in, we’re reiterating our devotion to G-d’s Word. It’s so important to us that we need to read it even when we can’t make practical use of it- and this lesson in itself proves to be practical in the truest sense.
