I agree completely. This was my readings of Romans as well, in addition to the fact that teachings of Old testament was "reset" when Jesus died on the cross. We no longer had to sacrifice animals to make up for sins, or pray in tabarnacle or anything else. All we had to do was believe that Jesus was the Son of God, and he was the lamb of God was was sacrificed for the sins of Humanity and we have to follow his teachings by making ourselves constantly walking on the path to the Kingdom of Heaven, correcting ourselves continuously everytime we veer off.
