God graciously removes sin—making the unclean clean—so that those He calls can boldly speak on His behalf.
In the year that King Uzziah died (around 740 BC), Isaiah received a profound vision of the heavenly throne room, located in the temple at Jerusalem, the capital city of the southern kingdom of Judah. During this vision, the prophet realized his own sinful state and cried out that he was “a man of unclean lips” dwelling among a people of unclean lips (Isaiah 6:5). In response, a seraph (a fiery angelic being) flew to him with a burning coal taken from the altar, signifying both the holiness of God and the means for atonement. This encounter occurred within the context of temple worship, where offerings were made and sacrifices were performed—practices that symbolically cleansed sinners so that they might draw near to a holy God.
In Isaiah’s own words, the angelic being “touched my mouth with it and said, ‘Behold, this has touched your lips; and your iniquity is taken away and your sin is forgiven.’(v.7).” The coal, heated by the fire on God’s altar, portrayed sin being consumed and purified. Just as the priests of Israel had to wash themselves before serving in God’s presence, here Isaiah experienced a similar yet supernatural cleansing to prepare him for prophetic ministry. That divine act of forgiveness foreshadows the fuller cleansing offered in the New Testament, where Jesus’s sacrifice removes the guilt of sin and invites believers to stand blameless before God. Ongoing fellowship with God is only possible through His provision of holiness; this principle is seen elsewhere in Scripture through symbolic washings that represent forgiveness and restoration (see commentary on washings in Exodus, which illustrate the need for continual cleansing in order to enter God’s presence).
The result of this purifying moment was Isaiah’s readiness to become God’s messenger. Immediately after his cleansing, he heard the voice of the Lord calling, “Whom shall I send, and who will go for Us?” (Isaiah 6:8). Because Isaiah’s iniquity had been dealt with, he was free to respond with faithful obedience, confident in his calling. This verse reminds us that true service to God begins with His merciful act of grace, enabling unworthy people to represent Him.
