You say Jesus fulfilled the Law – past tense. So now we don’t have to fulfill any of it? It’s already been totally fulfilled for us?
For what the law was powerless to do in that it was weakened by the sinful nature, God did by sending His own Son in the likeness of sinful man to be a sin offering. And so He condemned sin in sinful man, in order that the righteous requirements of the law might be fully met in us, who do not live according to the flesh but according to the Spirit.
Romans 8:3-4
