We are to watch, and not be found sleeping:

Mark 13:35 Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning:

  36 Lest coming suddenly he find you sleeping.

We are to watch, and not be found sleeping:

Romans 13:11 And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed.

I Thessalonians 5:6 Therefore let us not sleep, as do others; but let us watch and be sober.

Yet, all ten virgins sleep:

Matthew 25:1 Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom.

  5 While the bridegroom tarried, they all slumbered and slept.

What does that mean?

Are we like them, sleeping at the very end?

Mark 14:37 And he cometh, and findeth them sleeping, and saith unto Peter, Simon, sleepest thou? couldest not thou watch one hour?

Or are we, God forbid, possibly like these?

Isaiah 56:10 His watchmen are blind: they are all ignorant, they are all dumb dogs, they cannot bark; sleeping, lying down, loving to slumber.
