If "love is the fulfilling of the law," does love replace the Old Testament law (the Ten Commandments or the Mosaic Law)? And is there a contradiction between what the Apostle Paul said in Romans 8:3-4 about "the righteousness of the law being fulfilled in us" by the Jesus Christ condemning sin in the flesh and what he says in Romans 13:8-10 about love fulfilling the law? Can I become righteous simply by being loving?
