McConkie The Promised Messiah p 390-391
“Sabbath worship, that system which singles out one day in seven to be used exclusively for spiritual things, is a sign which identifies the Lord’s people. ...True religion always has and always will call for a Sabbath on which men rest from their temporal labors and work exclusively on spiritual matters. True religion requires-it is not optional; it is mandatory-that one in seven be devoted exclusively to worshiping the Father in Spirit and in truth. Without a Sabbath of rest and worship, men’s hearts will never be centered on the things of the Spirit sufficiently to assure them of salvation....It is in no sense an exaggeration nor does it overstate the fact one whit to say that any person who keeps the Sabbath, according to the revealed pattern, will be saved in the celestial kingdom.”
