Ephesians 5:14-17 (KJV)
14 Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.
15 See then that ye walk circumspectly, not as fools, but as wise,
16 Redeeming the time, because the days are evil.
17 Wherefore be ye not unwise, but understanding what the will of the Lord is.
