Isaiah 6:1–8 gives us a powerful glimpse into the holiness of God. Isaiah sees the Lord exalted on His throne, surrounded by seraphim who cry out, “Holy, holy, holy is the Lord of hosts,” declaring God's complete and perfect holiness. The overwhelming presence of God exposes Isaiah’s own sinfulness, leading him to confess his unworthiness. Yet, in God’s mercy, Isaiah’s guilt is removed and his sin atoned for through a coal from the altar. In response to God's cleansing and call, Isaiah offers himself willingly, saying, “Here I am! Send me.” This passage reveals that God's holiness both humbles us and transforms us for His purposes.
