It is already the hour for us to be awakened from sleep; for now is our salvation nearer than when we believe. The night is almost gone, and the day is at hand. Let us therefore lay aside the deeds of darkness and put on the armor of light.
Romans 13:11-12

All things become visible when they are exposed by the light, for all that is making manifest is light. Wherefore, the Lord God is saying, “Awake, sleeper, and rise from the dead, and Christ will shine on you.”
Ephesians 5:13-14

You are sons of light and sons of the day. We are not of the night nor of darkness. Consequently, we should not be asleep, even as the rest, that we may be watching and self-controlled.
I Thessalonians 5:5-6

Wake up, and establish the rest who are about to die; for I have not found your acts completed in the sight of my God. Remember how you have obtained, and hear, keep and repent. If ever you should not be watching, I will be arriving on you like a thief, and you will not know the hour I come.
Revelation 3:2-3
