Doctrines of Salvation 3:48; “NO PEACE AGAIN UNTIL CHRIST COMES. Peace has been taken from the earth, and it will not return until Christ comes to bring it. When that day arrives, he has promised to “send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity,” but when that day comes, he further says, “then shall the righteous shine forth as the sun in the kingdom of their Father.””
John 14:27; “Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.”
Either the Mormon Church is lying or Jesus is – you pick.
