That verse by itself might sound like it means one thing but when you compare scripture with scripture and rightly divide the word it makes perfect sense what it means.
Why would anyone want to abide by the old law when its clear that it is like putting a blanket over a rotting corpse, it just gets you by temporarily. It was never meant to be followed after Jesus's death. It also teached spiritual lessons using the physical because they just couldn't understand spiritual things. The law can't be followed exactly anyway, that's the whole point.
So jesus came to do away with the law? Sweet. He should have just said that.
