And he will take upon him death, that he may loose the bands of death which bind his people; and he will take upon him their infirmities, that his bowels may be filled with mercy, according to the flesh, that he may know according to the flesh how to succor his people according to their infirmities." (Alma 7:11-12)
To finish His Atonement King Benjamin says this:
"And he shall rise the third day from the dead; and behold, he standeth to judge the world; and behold, all these things are done that a righteous judgment might come upon the children of men." (Mosiah 3:10)
This is the reason we celebrate Easter, we are celebrating the things the Lord has done for us, we celebrate not his death but His Resurrection, the Lord is not dead but HE LIVES! This is my testimony to all who men and women everywhere.
