3 Nephi 12:17-20

"Do not think that I have come to nullify the law of Moses nor the writings of the prophets. I have not come to nullify but to fulfill. I truthfully tell you that not one bit of the law has passed away. Rather, it has all been fulfilled in me. I have given you my Father's law and commandments so you will believe in me, repent of your sins, and come to me with a broken heart and a humble spirit. You have the commandments before you, and the law is fulfilled. Therefore, come to me and saved. Truly, there is no other way to enter the kingdom of heaven except by following my commands which I have been giving you now.
