Antinomianism means 'against the existence of the law.' Such a person assumes that the salvation given by Christ frees a person to live in disregard for the law. But we can't live that way -- that is the way sinners live. There is no neutral ground.
What shall we say, then? Shall we go on sinning so that grace may increase? By no means! We died to sin; how can we live in it any longer? Or don't you know that all of us who were baptized into Christ Jesus were baptized into his death?
-- Romans 6:1-3 NIV.
