The Law was given to us as a school master, to show us our own sin. Just as in a mirror shows us our physical features clearly. Through the Law we see that we are liars, thieves, lustful, hateful, and disobedient to God in many ways. This is the purpose of the Law. To show us how impossible it is to obey and fulfill the Law.
Though we have the Law still and we should obey the Law, because it is God’s command. We are not saved by the Law. For if it saved us there would have been no reason for Jesus to come, and to become the perfect sacrifice for our sins. But we look to it as an example for us of how to live holy and righteous lives.
We are saved by our Faith and live upon our Faith in Christ who is the Son of God. We are law breakers and Jesus Christ is our redeemer, who paid a great price. The steep cost that had to be paid, to satisfy the righteous wrath of God, for the punishment we deserve for our sins. He fulfilled the Law perfectly.
So now our Faith in God, our love for God, and what He has done will cause us to obey His Law. We will love, follow, and obey His Law and the Spirit of God will abide with us and help us do that very thing.
7 Know then that it is those of faith who are the sons of Abraham. 8 And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, “In you shall all the nations be blessed.” 9 So then, those who are of faith are blessed along with Abraham, the man of faith. 10 For all who rely on works of the law are under a curse; for it is written, “Cursed be everyone who does not abide by all things written in the Book of the Law, and do them.” 11 Now it is evident that no one is justified before God by the law, for “The righteous shall live by faith.” 12 But the law is not of faith, rather “The one who does them shall live by them.” 13 Christ redeemed us from the curse of the law by becoming a curse for us—for it is written, “Cursed is everyone who is hanged on a tree”— 14 so that in Christ Jesus the blessing of Abraham might come to the Gentiles, so that we might receive the promised Spirit through faith.
