2 Nephi 2:8

Wherefore, how great the importance to make these things known unto the inhabitants of the earth, that they may know that there is no flesh that can dwell in the presence of God, save it be through the merits, and mercy, and grace of the Holy Messiah, which layeth down his life according to the flesh, and taketh it again by the power of the spirit, that he may bring to pass the resurrection of the dead, being the first that should rise.

So it’s very important to teach these things to everyone on earth. They need to know that no one can live with God except through what the Holy Messiah has done. He gives up his life and then takes it back by the power of the Spirit. This way he can make dead people come back to life. He was the first to come back from death.

This is why it’s so important to tell everyone on earth: no human being can stand before God except through the worthiness, mercy, and grace of the Holy Messiah. He will give up his life in the flesh and take it back up again by the power of the Spirit, so he can bring about the resurrection of the dead. He will be the first to rise.
