The church in Sardis suffered from spiritual slumber. It's easy for us to walk around and look spiritually correct when, in fact, our vital relationship with God is dead. The Lord said to the Sardis church, "Now wake up! Strengthen what little remains, for even what is left is at the point of death. Your deeds are far from right in the sight of God" (Revelation 3:2).
If we are not careful, sleep can sneak up on us, even at the wheel of a car. The psalmist said, "I long for the Lord more than sentries long for the dawn, yes, more than sentries long for the dawn" (Psalm 130:6). The watchman's entire occupation is based upon staying awake, intently gazing at the darkness for any sign of the enemy. If he falls asleep, disastrous consequences can result for the entire city.
Instead of sleeping, the watchman eagerly looks to the eastern sky for signs of the morning sun. In the same way, our souls should have an eager expectation for God, a quickened excitement every time we spend time alone with Him.
Amos said, "How terrible it will be for you who lounge in luxury and think you are secure. . . ." (Amos 6:1). Stir yourself up, for the Lord "will come upon you suddenly, as unexpected as a thief" (Revelation 3:3).
