Isaiah 6:1-7 (ESV)

1 In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. And one called to another and said:

“Holy, holy, holy is the Lord of hosts;

the whole earth is full of his glory!”

And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. And I said: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!”

Then one of the seraphim flew to me, having in his hand a burning coal that he had taken with tongs from the altar. And he touched my mouth and said: “Behold, this has touched your lips; your guilt is taken away, and your sin atoned for.”

Habakkuk 1:12-13 (ESV)

12  Are you not from everlasting,

O Lord my God, my Holy One?

We shall not die.

O Lord, you have ordained them as a judgment,

and you, O Rock, have established them for reproof.

13  You who are of purer eyes than to see evil

and cannot look at wrong,

why do you idly look at traitors

and remain silent when the wicked swallows up

the man more righteous than he?

Romans 1:18-20 (ESV)

18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. 19 For what can be known about God is plain to them, because God has shown it to them. 20 For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
