In so far as it is applicable I certainly support following the Law, though I am imperfect and have been known to sin. Of course, there are a couple important points when speaking of the Law and its fulfillment. First and foremost: Paul and the early church maintained a distinction between God's Law and the Mosaic Law and the traditions of men. God's Law, or the Spirit of the Law, is what is important. Under the New Covenant, God's Law is written on our very hearts. By means of study of the Mosaic Law and the Prophets, along with prayer and a sincere heart for God and truth, one may come to know God's Law.
Secondly: the Mosaic Law was given to the Jews, it is the Old Covenant. While this Covenant has not gone away - the Jewish People are still God's People, he is still their God, as per their covenant - we Gentiles are not required or expected to adopt it as such. No physical circumcision required, but rather circumcision of the heart. We are to follow God's Law, the Spirit of the Law, but we are not required to follow the letter of the Law. Hence Paul teaches that we are Spiritual Jews, part of Spiritual Israel.
Thirdly: The New Covenant did not toss out the Old, but the Old still exists alongside the New - at least for the time being. When the judgement is complete and the heavens and earth are remade, then I believe the Old Testament will be gone.
