Jesus said the law will last forever. That means all 613 laws scattered in the Torah are in effect. We have no hope of keeping that law. Therefore we must accept the grace through faith that Jesus gave us on the cross. All who reject Him will face judgment based on the law. We acknowledge the law is in place when we admit that we sin since sin is transgression of the law.
JESUS saw our struggle and had mercy on us and came to earth to die on the cross satisfying the penalty of us breaking GOD's law but Its always been Grace through faith to be saved or be perfect to GOD In their own strength and no one could be perfect to GOD In their own strength.
