Being under grace does not mean that we are anti-law or say that the law is evil – God forbid!
Romans 7 “7 What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law….12 So then, the law is holy, and the commandment is holy, righteous and good.”
God was not harsh when He gave the law.
God never makes mistakes.
When He created the world, everything was good.
Even the Tree of knowledge of good and evil is good.
It was good because it accomplished the purpose of drawing out the inherent sin of Adam.
God did not make a mistake by giving the Law.
The Law is holy, perfect and righteous.
The reason He gave the law was to show people that they are sinners.
The law demanded absolute perfection. Therefore even one violation brought death.
The only way to forgive sins is by shedding of blood (death).
God told Israel to offer the animal sacrifices (shedding of imperfect blood) as a placeholder/temporary covenant until Jesus Christ would come.
Matthew 5 “17 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.”
Jesus Christ, the Son of God came and He fulfilled the law by being the only perfect human who never sinned.
He also fulfilled the requirement for the punishment of the law for our sins by dying on the cross. He rose from the dead having forgiven us and declaring us righteous by grace received through faith.
Therefore Jesus Christ’s grace is the fulfillment of the law.
Hebrews 10 “8 First he said, “Sacrifices and offerings, burnt offerings and sin offerings you did not desire, nor were you pleased with them”—though they were offered in accordance with the law. 9 Then he said, “Here I am, I have come to do your will.” He sets aside the first to establish the second. 10 And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all.“
Without the law, Christ could not come to bring grace.
The law is given to shut the mouths of the self-righteous (sinner) who trusts in his own works.
The law actually empowers sins and is supposed to make the person despair and come to Jesus Christ to receive grace.
This is why the unbeliever is condemned under law but he can come to Jesus to be declared perfect and righteous by faith!
Therefore Grace is the true fulfillment of the law.
Without law, there is no grace.
Romans 3 “31 Do we, then, nullify the law by this faith? Not at all! Rather, we uphold the law.”
But once you are under grace, you are free from the law!
Galatians 3 “24 So the law was our guardian until Christ came that we might be justified by faith. 25 Now that this faith has come, we are no longer under a guardian.”
Romans 6 “14 For sin shall no longer be your master, because you are not under the law, but under grace.”
When we are under grace, we are righteous, perfect forgiven, saints, children of God.
We are not lawless rebels but we are in Christ who teaches us to love one another to fulfill the law.
