Thoughts on this apologetic

[Wyrd of Gawd]

Lek, your referring to the jesus sacrifice fulfilling the sacrificial law of the old testament, so basically he covered the atonement for our sins. Does that mean that Christians do not have to follow these laws or do they just have no accountability when they break them?

We are required to follow the moral requirements of the law as summed up in the two great commandments.  

Matthew 22:37-40New International Version (NIV)
37 Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’[a] 38 This is the first and greatest commandment. 39 And the second is like it: ‘Love your neighbor as yourself.’ 40 [b]All the Law and the Prophets hang on these two commandments.”

Did Jesus create a new commandment when he said: "Love your neighbor as yourself"?  He made up a lot of new ones in the Sermon on the Mount.
