“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.”
Now I am a deist not a christian so I don't have a dog in this fight but it appears to me that the christian re-constructionist movement is more correct on this one.
The Law is still here and it serves to convict us of our sin that we will never be rid of...and so we realize we need a savior. Read Romans 6 and 7 for a discussion of law and grace.
