Hi Leibowde84,
Matthew 23:1-3
1. Then Jesus spoke to the multitudes and to His disciples,
2. saying: "The scribes and the Pharisees sit in Moses' seat.
3. "Therefore whatever they tell you to observe, that observe and do, but do not do according to their works; for they say, and do not do.
Jesus is born under the law, therefore that law should be followed since this is originated from God handed down to Moses. One instances, Jesus called the Pharisees as hypocrites because of their legalistic acts. They like to display in front of the Jews to show that they are a holy and religious teachers of the law, but their hearts is not true to God. Jesus respects the law, but He is sent by the Father to amend the law.
Matthew 12:8
8. "For the Son of Man is Lord even of the Sabbath.''
Rom. 6:14
14. For sin shall not have dominion over you, for you are not under law but under grace.
Jesus is the Lord of the Sabbath. It looks like He violated the Sabbath, but that He did it to show to the Jews that we are saved by faith under the grace of God.
Rom. 7:6
6. But now we have been delivered from the law, having died to what we were held by, so that we should serve in the newness of the Spirit and not in the oldness of the letter.
On this verse, it says that we are free and delivered from the law. That means free from the bondage and slavery of the law—legalism.
Gal.4:4-5
4. But when the fullness of the time had come, God sent forth His Son, born of a woman, born under the law,
5. to redeem those who were under the law, that we might receive the adoption as sons.
Jesus came to redeem who are under the law, and to qualify us—as adopted sons of God.
Heb. 10:1
1. For the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices, which they offer continually year by year, make those who approach perfect.
One example is the atonement (practices) in the Old Testament, they offered sacrifices to God by blood sprinkling for the purpose of cleansing their sins. But now in the New Testament, Jesus laid down His life (once for all) to served as the atonement—who shed His blood on the cross for the salvation of many.
