As much as I enjoy getting a good night’s sleep, about the only positive thing that comes from it is the energy and alertness to have a productive day after I wake up. While we understand the need to get enough sleep, it is only when we are awake that our goals are accomplished. Spiritually speaking though, sleep is acceptable to God only in physical death; those who have physically died are said to be asleep (1 Corinthians 15:51).
Otherwise, one is in a very dangerous spiritual condition if he is described as being asleep (1 Thessalonians 5:6). Jesus’ very sobering call to the entire church in Sardis (Revelation3:2) was to wake up! They had fallen asleep.
