Prior to these words recorded by Isaiah, we find in chapter 5 a sobering description of God’s people, whom He loves, but who have turned away from Him. Although He continues to stretch out His hand to them, their pride prevents them from seeing and returning to Him. Even as God judges them for their sins, His heart remains wide open for them to change their hearts, return, and once more walk in His ways.
It is only after King Uzziah dies that Isaiah sees the Lord and experiences a life-changing encounter with Him as a “live coal” is brought to his lips, representing the purging of his sin. Seeing God brings Isaiah to a place of deep repentance. He bends his heart to personally confess the very thing that has separated the people from the Lord: “I am undone…a man of unclean lips…I dwell in the midst of a people of unclean lips.” With these words, Isaiah expresses a heart and life change so deep as to rule out forever any return to his former way of life. Having received the Lord’s touch, he has become a new man. His iniquity is taken away, his sin purged, his lips cleansed by holy fire. This is nothing less than precise spiritual surgery that renovates his soul. But it doesn’t stop there. Isaiah’s inner transformation now enables him to hear and respond to the clarion call from God: “Whom shall I send, and who will go for Us?
God’s people have lost their way. Because they have drifted away from their King—God—they no longer know who they are. God looks intently for a representative, even one person who possesses His Spirit and desire. Hope for change still remains because God is long-suffering in issuing His call. Driven by his profound inner change, Isaiah responds positively to God’s call. Any who seek to go without an internal change will be overcome by the spirit of the age. Isaiah cries, “Here am I! Send me.” No conditions and no strings attached. Just utter, unflinching obedience regardless of what he sees or hears or is called to do. As we “go,” not everything will be a spender and enjoyable, but knowing that the Father is with us will make it an honor and a delight to walk it out.
