But it does affect ones standing in heaven
Matthew 5:17-20
17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. 18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. 19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven. 20 For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
There are a lot of anti-nomian pastors (and Freepers) who are going to find themselves making it to heaven as the "least in the kingdom" because they teach their congregations and their audience that it is ok to violate G-d's written Torah with impunity and wear it as a badge of honor.
You're failing to see the difference between the letter of the Law and the Spirit of the Law. The New Testament says you are cursed if you keep all the Law and fail in even one point. That's the entire human race other than Jesus Christ. James says if you break one you're guilty (essentially) of breaking them all.
Salvation is not a license to sin, but the Scripture is clear: No flesh shall be justified by the Law.
This is the whole point of Peter trying to get the people to follow the Law in addition and Paul rebuking him.
However, I've been through this before and it usually doesn't ever get resolved.
