Isaiah 6:7 Meaning: The Coal That Takes Away Sin
He touched my mouth with it, and said, “Behold, this has touched your lips; and your iniquity is taken away, and your sin forgiven.”
And he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged.
and he touched my mouth with it, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin forgiven.
and he striketh against my mouth, and saith: `Lo, this hath stricken against thy lips, And turned aside is thine iniquity, And thy sin is covered.'
and he made it touch my mouth, and said, Behold, this hath touched thy lips; and thine iniquity is taken away, and thy sin expiated.
Meaning in one sentence
Isaiah's guilt is removed when a seraph touches his lips with a live coal from the altar. What this means for forgiveness and calling.
Context
Isaiah had come undone. He saw the Lord seated high and lifted up, with seraphim calling out, “Holy, holy, holy.” The temple shook. Smoke filled the house. In that overwhelming brightness, Isaiah could only cry, “Woe is me! I am undone, a man of unclean lips.” He knew his sin, especially the words he had spoken, were not fit for the presence of the King. But instead of destruction, a seraph flew to him carrying a live coal taken from the altar, the altar of incense in the heavenly sanctuary. With that coal the seraph touched Isaiah’s mouth and declared his iniquity removed, his sin atoned for. Immediately, Isaiah heard the Lord ask, “Whom shall I send?” and he was ready to answer, “Here I am. Send me.” The vision moves from holy dread to clear commission, with a moment of cleansing at the center.
Key Words
Three Hebrew words carry the weight of this moment. First, the verb naga, “touched.” It is a gentle, deliberate contact, not a strike. The same verb describes the seraph laying the coal on Isaiah’s mouth. This is not punishment; it is application. God brings the remedy right to the place of shame.
Second, the word translated “taken away” is sur, meaning to turn aside or remove. Picture something that was blocking the path being pushed out of the way. Isaiah’s guilt is not just hidden; it is removed from standing between him and God.
Third, the verb for “forgiven” or “atoned for” is kaphar, to cover, to make atonement. This is the same word used for the mercy seat on the ark, where blood was sprinkled on the Day of Atonement. The coal came from the altar, the place of sacrifice. So the forgiveness Isaiah received was not cheap; it came through the offering that the altar represented. The coal itself had no power, but it was a visible sign of a real atonement God was making.
How Christians Read This Verse
John Calvin described the coal as a sacrament, a visible sign that confirms what God is doing. He stressed that the coal had no power in itself; only God can cleanse. The Cambridge Bible sees three meanings in the act: contact with divine holiness is not necessarily destructive, fire purifies, and the altar points to atoning sacrifice. Matthew Henry reads it as a declaration of pardon that prepares Isaiah for service. Barnes notes that fire was a common emblem of purifying in the ancient world, and that the real effect was the removal of Isaiah’s sense of unworthiness so he could deliver God’s message. Across these views, all agree: the cleansing is God’s work, the altar points to sacrifice, and the result is a prophet ready to be sent.
A common misunderstanding
Some readers imagine the live coal burned away Isaiah’s sin, as if the fire itself destroyed the impurity. In fact, the coal is not a cleansing agent with magic power. Calvin warned against this very idea. The coal is a visible sign, a “sacrament” as he called it. The real cleansing comes from God’s declaration: “Your iniquity is taken away, your sin forgiven.” The altar from which the coal was taken points to the sacrifice that makes atonement. The touch was gentle, momentary, a gesture of grace, not a painful ordeal.
Living This Out
This week, you may feel unworthy to pray, to speak about your faith, or even to ask God for anything. Perhaps your own words, gossip, lies, harsh speech, echo in your mind. Isaiah’s story shows that God meets you exactly where you feel dirtiest. You do not have to clean yourself before you come to Him. The altar of Christ’s sacrifice stands ready. Bring your unclean lips to the cross. Let God touch them with the promise He spoke to Isaiah: your sin is taken away. Then rise and ask what He would have you do. The cleansing comes first; the calling follows.
Main takeaway: The holiness that exposes our sin is the same holiness that removes it, through the sacrifice God provides at His altar.
For Families
For ages 5, 8
Isaiah saw God and felt very scared because he had done wrong things. But God sent an angel to touch Isaiah’s mouth with a special coal. That meant God forgave him. When we tell God we are sorry, He forgives us too.
For ages 9, 12
Isaiah knew his words had been sinful, and he felt unworthy to be in God’s presence. But God did not reject him. The coal from the altar represented the sacrifice that would one day take away all sin. After God cleansed Isaiah, he was ready to serve. When we confess our sins, God cleanses us and gives us a purpose too.
Questions People Ask
What was the live coal that touched Isaiah's lips?
It was a red-hot ember taken from the altar of incense in the heavenly temple (some traditions see it as from the altar of burnt offering). The coal was not magical; it served as a visible sign of the atoning sacrifice. The touch was gentle, not burning, and signified that Isaiah's sin was removed by the altar's offering.
Why did the seraph touch Isaiah's mouth specifically?
Isaiah had confessed that his lips were unclean. The mouth was the part he felt most guilty about, and also the part he would use to speak God's message. The cleansing targeted the area of his shame and prepared him to speak as a prophet. It echoes how God later touched Jeremiah's mouth (Jeremiah 1:9) to put words in it.
Does this verse mean we need a physical object to be forgiven?
No. The coal was a symbol, not the source of forgiveness. Calvin called it a 'sacrament', a visible sign that confirms what God does invisibly. Christians believe forgiveness comes through faith in Christ's sacrifice, not through any object. The coal pointed to the atonement that Christ would accomplish once for all.
How is this verse connected to Jesus?
The altar from which the coal was taken represents the place of sacrifice. Many Christians see it as a foreshadowing of Christ's cross. Isaiah 53:5 says 'he was pierced for our transgressions' and 'by his wounds we are healed.' The verb for 'forgiven' here (kaphar) is the same word for atonement throughout the Old Testament, which Jesus fulfills.
What does 'your iniquity is taken away and your sin forgiven' actually mean?
It means God removed the guilt and penalty of Isaiah's sin. The Hebrew verb 'taken away' (sur) means to turn aside or remove, the sin no longer blocks the relationship. 'Forgiven' (kaphar) means covered or atoned for, as by a sacrifice. Together they declare that Isaiah is fully cleansed and restored to fellowship with God, ready to serve.
