Jesus' earthly ministry was only to the Jews.
Matthew 15:24 But He answered and said, "I was sent only to the lost sheep of the house of Israel." NAS
After the Jews rejected and crucified their Messiah, the resurrected Lord then commanded His apostles to take His gospel to the whole world. The Gospel of Jesus Christ is the New Covenant that replaced the Covenant of the Law. I suggest you study Hebrews before you decide you have any idea of how Christians are to view the Law.
Christians are under the New Covenant, which replaced the Old Covenant. The New Covenant can be summed up in just two commandments. Love the Lord your God with all your heart, soul, and mind, and love your neighbor as yourself.
