Isaiah met the Lord as described in the riveting passage of Isaiah 6. He saw himself as under judgment—under the sentence of death. But then, through his interaction with the Lord, He was wonderfully cleansed and redeemed. His salvation was free; it cost him nothing.
The Lord then expressed a need for someone to represent Him. The Lord needed something? Yes, the Lord needed someone to go. Isaiah was so grateful for his new sanctified life that he offered to be the one to be sent.
Most of the time we focus on the first half of Isaiah 6, in fact, there are entire sermons on this part of the chapter. We get it. So we move on. But that is like reading the first half of a long email and skipping the rest. But wait! In the last part of the chapter we see that Isaiah was to stay on mission, keep on task, even though the road ahead would be difficult. The record shows that Isaiah persevered. Would you, you who have also been redeemed, do the same?
Weep with us; pray with us to the Lord of the Harvest to send laborers into His harvest. Just as our willingness to accept the Lord as Savior is a transaction between us and the Holy Spirit, so the decision to accept an assignment to disciple the nations is a transaction between you as a Christ-follower and the Holy Spirit. Follow that prompting by researching assignments that are surprisingly well suited to you.
