It (trying to keep the law) grants you the power to judge others and feel superior to them. You believe you are living to a higher standard than those you judge. Enforcing rules, especially in its more subtle expressions like responsibility and expectation, is a vain attempt to create certainly out of uncertainty. And contrary to what you might think, I have a great fondness for uncertainty. Rules cannot bring freedom; they only have the power to accuse.
Moses, without any mercy, breaks all bruised reeds, and quenches all smoking flax. For the law requires personal, perpetual and perfect obedience from the heart, and that under a most terrible curse, but gives no strength. It is a severe task master, like Pharaoh's, requiring the whole tale ofbricks and yet giving no straw. Christ comes with blessing after blessing, even upon those whom Moses had cursed, and with healing balm for those wounds which Moses had made.
