Sacrifice

3 Nephi 9:20

"And ye shall offer for a sacrifice unto me a broken heart and a contrite spirit. And whoso cometh unto me with a broken heart and a contrite spirit, him will I baptize with fire and with the Holy Ghost, even as the Lamanites, because of their faith in me at the time of their conversion, were baptized with fire and with the Holy Ghost, and they knew it not."

Physical sacrifices were done away when Jesus was sacrificed. In their place, we must sacrifice our hearts and spirits. We must give them to the Lord and devote our lives to Him so that He can use us for good. Having a broken heart is when we are sufficiently humble and know that we are nothing compared to God. A contrite spirit has to do with feeling remorse for sin and wrongdoings. These sacrifices mean we want to change from our natural selves and be more like the Savior. It is an ongoing process, daily implemented.
