Isaiah 6:1-7 (NIV)
1 In the year that King Uzziah died, I saw the Lord, high and exalted, seated on a throne; and the train of his robe filled the temple.
2 Above him were seraphim, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying.
3 And they were calling to one another: “Holy, holy, holy is the Lord Almighty; the whole earth is full of his glory.”
4 At the sound of their voices the doorposts and thresholds shook and the temple was filled with smoke.
5 “Woe to me!” I cried. “I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the Lord Almighty.”
6 Then one of the seraphim flew to me with a live coal in his hand, which he had taken with tongs from the altar.
7 With it he touched my mouth and said, “See, this has touched your lips; your guilt is taken away and your sin atoned for.”
Isaiah 60:1-3 (NIV)
1 “Arise, shine, for your light has come, and the glory of the Lord rises upon you.
2 See, darkness covers the earth and thick darkness is over the peoples, but the Lord rises upon you and his glory appears over you.
3 Nations will come to your light, and kings to the brightness of your dawn.
Romans 13:11-12 (NIV)
11 And do this, understanding the present time: The hour has already come for you to wake up from your slumber, because our salvation is nearer now than when we first believed.
12 The night is nearly over; the day is almost here. So let us put aside the deeds of darkness and put on the armor of light.
John 3:19-21 (NIV)
19 This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil.
20 Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed.
21 But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God.
