This message is based on Isaiah 6 and is a consideration of the call of Isaiah to be God's prophet, with a reading and explanation of the text. We see Isaiah's personal experience of encountering God in his holiness as Sovereign King of the universe resulting in his conviction of guilt and need for divine cleansing. Then from a position of a provided atonement he hears and answers the call of God to be his special prophet. What kind of commission is this when he is informed that people will not listen and repent so judgment is decreed? But in the midst of wrath and judgment God remembers mercy in accord with his covenant promises to send the Seed who is Jesus the Messiah..
