If Jesus did not die for all your sins at Calvary, you have to live under the law, for sin is transgression of the law. Therefore, your sin can condemn you. If that is the case, you must have right standing before God of obedience to the law, Paul is adamant, you do not have a righteousness before God of obedience to the law EG Rom 10:4,, Gal2:21, Phil 3:9, Rom 3:22&23
