Joseph F. Smith, Journal of Discourses — Volume 19…
“ That which we call death is merely the slumber and rest of this mortal clay, and that only for a little season, while the spirit, the life, has gone to enjoy again the presence and society of those from whence it came, and to whom it is joy again to return. And this will be the condition of the righteous until the morning of the resurrection, when the spirit will have power to call forth the lifeless frame to be united again, and they both become a living soul, an immortal being, filled with the light and power of God. ”
