Romans 8:1 There is now no condemnation for those who are in Christ Jesus. For in Christ Jesus the law of the Spirit of life has set you free from the law of sin and death. ----
When Jesus died and rose again, he fulfilled the law. If you remember when Mary Magdalene went to anoint the body of Jesus in His tomb, the body was gone. She went off crying. She was met by Jesus who asked her why she crying. When she realized who He was, she tried to hug Him. Jesus told her not to touch Him, for He hasn't ascended to His Father yet. In other words the blood was still fresh on His body. He hadn't made the offering to His Father yet. Once the blood was offered for the remission of sins, the penalty had been done away with. The new testament says, oh death where is thy sting? We are under the righteousness of the law, but we don't have to die now. We are to obey his law, with the help of the Holy Spirit.
Fulling the Law is rabbinic term that meant to interpret the Law in a way that added meaning, filled it up with meaning, or to demonstrated a full understanding of the Law through words or by example. One the other hand, to abolish the Law referred to interpreting it in a way that subtracted meaning or undermined it. In Matthew 5:17, Jesus was about to teach against what the teachers of the Law had been teaching, which would have sounded to them like he was undermining the Law, so he proceed it by saying that he came not to undermine the Law, but to fully teach it, and then proceeded to fulfill the Law six times. According to Titus 2:14, Jesus did not give himself to redeem us from the Law, but to redeem us from Lawlessness and to purify for himself a people of his own possession who are zealous for doing good works. The Law is God's instructions for how to do good works (2 Timothy 3:16-17), which is why the Jews in Acts 21:20-24 had become zealous for the Law.
In Romans 7:21-25, Paul said that he wanted to do good, that delighted in God's Law, and that he served the Law of God with his mind, but contrasted that with a law of sin that caused him not to do the good that he wanted to do, that held him captive, and that he served with his flesh. So in Romans 8:1-2, we should not conflate the Law that Jesus fulfilled with the law of sin and death because Paul just contrasted the two, but rather it is God's Law that is the Law of the Spirit of life that Jesus fulfilled by teaching how to correctly obey it by word and by example. The Mosaic Law without it's penalty remains instructions for how to do what is holy, righteous, and good, and how to avoid sin (Romans 7:12, Romans 7:7), and as part of the New Covenant, we are still told to follow God's instructions for how to do what is holy, righteous, and good (1 Peter 1:13-16, 1 John 3:4-10, Ephesians 2:10) and to avoid sin (Romans 6:15).
