Mosiah 15:20

"But behold, the bands of death shall be broken, and the Son reigneth, and hath power over the dead; therefore, he bringeth to pass the resurrection of the dead."

Christ died and 3 says later he was alive again.  Just as he was alive again, we will be alive again.  Resurrection is a gift that we all get. It is through Christ that that is made possible.
