Isaiah 6:3-7

 Water Baptism is for the repentance of sin and a public statement of your acceptance of Jesus as your Lord and Savior. It atones us from sin and makes us acceptable in the eyes of the Father…He sees His spotless Lamb in our place.

Jesus gives us baptism by fire. 

He gives us Holy Spirit who  resides in those who accept His Son for remission of their sins. He will accomplish in our lives what we are incapable of and get us safely home to our heavenly abode.

Isaiah 6:3-7

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

The whole earth is full of His glory!”

4 And the posts of the door were shaken by the voice of him who cried out, and the house was filled with smoke.

5 So I said:

“Woe is me, for I am undone!

Because 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.”

6 Then one of the seraphim flew to me, having in his hand a live coal which he had taken with the tongs from the altar. 7 And he touched my mouth with it, and said:

“Behold, this has touched your lips;

Your iniquity is taken away,

And your sin purged.”

The threefold repetition intensifies the superlative. For example, the “holy of holies” is the holiest part of the temple (the most holy place). This line is often translated as a statement, “the whole earth is full of His glory,” but it could also be translated as an invocation, “may His glory fill the whole earth”—looking ahead to the ultimate fulfillment of Yahweh’s visible earthly reign. The glory of Yahweh is His visible earthly presence. Isaiah’s vision recalls a past time in Israel’s history when Yahweh was visibly present among them. 

Isaiah is cleansed of sin so that he can remain in the divine presence and live to tell about it.

Atonement achieved a ritual cleansing of sin, usually by means of blood sacrifice. The Hebrew word used here can mean covering over or wiping away. Atonement restores the relationship between God and sinners. 

Isaiah’s atonement without sacrifice illustrates God’s freedom to extend mercy by His grace. Faithlife Bible

To say the word holy twice in Hebrew is to describe someone as “most holy.” To say the word holy three times intensifies the idea to the highest level. In other words, the holiness of God is indescribable in human language. To be holy means to be different, distant, or transcendent. Thus the song of the seraphim is a constant refrain that the transcendence of God is indescribable. 

Although the Lord is totally different from us—He is perfect—in His mercy He still reaches down to take care of us. 

The Hebrew word order is, “The fullness of all the earth is His glory.” 

We know that the glory of God transcends the universe yet in order to balance the expression of the transcendence of God in the first half of this verse, the words of the second half emphasize God’s closeness to His creation—His involvement with the earth and its people.

If even the doorposts of the heavenly temple shook in response to God’s holiness, how much more will the whole earth shake when the Lord visits it.

Confronted with this vision of the Lord, Isaiah realized that he was under judgment—that he was undone. He must have thought that he had come to the end of his life. Isaiah knew that he was a sinner. He realized that his lips were the only ones not giving God praise in that setting Isaiah’s plight is the plight of every person. No one, in his or her present state, is capable of standing before the Holy One. After contemplating the death of Uzziah, Isaiah had seen the King who will never die.

The live coal … from the altar symbolizes both the purification of blood and the fire of the Spirit that enabled the prophet to speak. From that point on, his words would be light to his hearers and power to those who would listen. 

The fact that a coal from the altar was used reminds us that ultimately all sin is forgiven because of a sacrifice. The sacrifices on the temple altar point to the ultimate sacrifice of the Savior Jesus. The Hebrew word translated purged means “covered” and is the same word that is translated atonement. NKJ Bible

Numbers 14:21 but truly, as I live, all the earth shall be filled with the glory of the LORD—

Psalm 72:19 And blessed be His glorious name forever! And let the whole earth be filled with His glory. Amen and Amen.

Jeremiah 1:9 Then the LORD put forth His hand and touched my mouth, and the LORD said to me:“Behold, I have put My words in your mouth.
