Matthew 5:17-20 Christ came to fulfill the law

"Jesus is Lord! This is the triumphant witness of the New Testament. The gospel proclaims that our Creator entered our world. It is a world enslaved to sin and opposed to him. And yet by grace he did not come to destroy it, but to redeem it — to provide a means for the forgiveness of sins, adoption into his family, and the restoration of all that he has made (John 1:1–14; cf. Romans 8:20–21). By his death, Jesus defeated God‘s enemies, and ours: sin, death, and the devil (1 Corinthians 15:25–26, 54–57; Colossians 2:14–15). His resurrection is an indisputable witness to his victory, and the sure promise that all who believe in him can share in his triumph (1 Corinthians 15:20–23). It also declares him to be the judge of all the earth (Acts 17:30–31). He has ascended as ruler of the universe, and he will return to destroy his enemies and to bring his people into the fulness of a new creation where we will live with him, face to face, forever (Revelation 21–22)."Keeping it Missional Porterbrook network.

Jesus lived what we could not "perfection" he died the death we could not die. When Jesus said he came to fulfill the law he was referencing that all that was required he came to do. The law required perfection, we know that we are not perfect. The joy in knowing that God has sent the perfect sacrifice for us brings joy and peace. I am so thankful that the law was fulfilled for me. I am so blessed that the gospel was preached to me. I could not live what the law required but Jesus lived it to the letter. In his life, death, and resurrection we are forgiven and redeemed. We are clothed in Christ righteousness and God views us as he views his son. Praise be to God who is rich in mercy and grace towards his kids.
