Having been provided with knowledge of the future and the glory of God, Isaiah feels inadequate to serve God. “Woe is me… I am a man of unclean lips“. Yet the seraphim reassures Isaiah that God can work with him, “your guilt is taken away, and your sin atoned for.” So when the voice of the Lord cries “Whom shall I send, and who will go for us?“, Isaiah willingly volunteers to be God’s messenger.
This is similar to our own situation. We’ve been called by God to serve Him, offered hope and a part of God’s future. Yet we feel unable to serve God, too inadequate to even share the message of hope we’ve been given. Like Isaiah, we should be reassured that God is with us, and be eager to share our hope with others.
Paul offers the Colossians advice on living this way. “Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom… do everything in the name of the Lord Jesus… continue steadfastly in prayer, being watchful in it with thanksgiving“.
