The Law demands perfect righteousness or beacons us to Faith in Christ

"The law, then, as a covenant of works, demands in the most authoritative manner, from every descendant of Adam who is under it, perfect holiness of nature, perfect righteousness of life, and complete satisfaction for sin. And none of the race of fallen Adam can ever enter heaven unless he either answers these three demands perfectly in his own person, or accepts by faith the consummate righteousness of the second Adam, who 'is the end of the law for righteousness to every one that believeth' (Romans 10:4)." - John Colquhoun, A Treatise On The Law and The Gospel
