steeped in lethargy

Spencer W. Kimball: [There] are Church members who are steeped in lethargy. They neither drink nor commit the sexual sins. They do not gamble nor rob nor kill. They are good citizens and splendid neighbors, but spiritually speaking they seem to be in a long, deep sleep.

They are doing nothing seriously wrong except in their failures to do the right things to earn their exaltation.
