“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.” Matt 5:17
Ending something vs. fulfilling (as in fulfilling an obligation or requirement) seems to be an important distinction. If the law is ended and I am released from any obligation to it, does that mean I am now free to kill or steal with no consequence as to my salvation or relation to the Creator of those laws?
Christ fulfilled the law, something that no one else could do. As for your question “does that mean I am now free to kill or steal with no consequence as to my salvation or relation to the Creator of those laws?” The Spirit Himself teaches us to love one another. If you are a believer, why would you want to kill your neighbor or steal from him/her? Do you really need a law to keep you from doing that?
