(I) Or, by a sacrifice for sin.
(a) Romans 8:3 what the law could not do in that it was weak through the flesh
"And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses." (Acts 13:39)
"Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law [is] the knowledge of sin." (Romans 3:20)
"For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. For the law made nothing perfect, but the bringing in of a better hope [did]; by the which we draw nigh unto God." (Hebrews 7:18,19)
"For the law having a shadow of good things to come, [and] not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect. For then would they not have ceased to be offered? because that the worshipers once purged should have had no more conscience of sins." (Hebrews 10:1,2)
"By the which will we are sanctified through the offering of the body of Jesus Christ once [for all]." (Hebrews 10:10)
"For by one offering he hath perfected for ever them that are sanctified." (Hebrews 10:14)
