Sermon C: 5 S Epiph: Is 6:5
On 2/4/07 the 3 readings assigned for the 5th Sunday after the Epiphany are Isaiah 6:1-13 (God confronts Isaiah); 1 Corinthians 14:12b-20 (Praying in tongues) and Luke 5:1-11 (The catch of fish). The text chosen to elaborate on is Isaiah 6:5 in which Isaiah laments, "Woe is me, for I am undone!"
It is not always that one finds such an obvious passage easily comprehended using the distinctions between Law and Gospel. While the first distinction between L&G involves their proper use, this passage indicates clearly a second distinction between "Living under the Law" in contrast to "Living under the Gospel." To "live under the Law" means to assume that your works make a difference to God as to whether you become saved and whether you remain saved. It's called legalism.
God confronts Isaiah in this chapter with Isaiah's response being, "Woe is me, for I am undone!" Note the reason for his fear. "Because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips." As James points out, the most damaging member of the body can be the tongue which often speaks words that one wishes he could take back but which is impossible to do.
Every religion of the world concludes that because God is so holy and almighty, the only task of the human being is to attempt to placate His anger and wrath directed toward us. Every religion lives under the Law assuming that our obedience or meditation or sacrifice or living right, etc. etc. will move God to love and accept us. The concept as revealed in Christianity that God loves you while you were his enemy and takes upon Himself the whole work of your salvation is simply unknown.
To Isaiah's astonishment and delight, God sends a seraphim angel to Isaiah to touch his mouth with a live coal from the altar. In the context of the Bible, who cannot realize that the only altar of sacrifice from which comes redemption is the cross of Christ? Note that both "iniquity" is taken away and "sin" is purged. The word "iniquity" refers to the punishment of sin that is removed from Isaiah while the word "sin" in the Hebrew points to the the offerings that are no longer required to offset one's sin!
Isaiah, living under the Law in fear of the holy God, receives the Gospel gift of forgiveness and righteousness. When God therefore asks whom shall He send to go for "Us" (the Trinity), Isaiah responds "Here am I! Send me!" That's how sanctification works! First God makes the move to redeem us; then we respond with delight and joy in taking up the privilege to obey His call.
