Sermon - Epiphany 5 - Isaiah 6:1-6

 


Sometime or another, we’ve all been caught in a lie.  It’s not a fun experience.  You dishonesty is exposed.  You stand convicted.  What will the other person say or do now?  Will they ever trust you again?  Do you try to double down and grow the lie with more deceit? Or do you fess up and humbly ask for forgiveness?

But what if it’s not just a white lie that snagged you, but a big one, a whopper?  And what if it’s not just another person that is calling you out, but a judge?  In fact, what if it’s the heavenly judge of all, the one who sits on the throne?  The one from whom there is no hiding, who cannot be fooled, who knows our every darkest, deepest sin, and by rights could call us to account.

That’s where Isaiah found himself in his vision of Yahweh, the Lord.  Sure it was an awesome sight – God himself enthroned over the temple, his throne, his robe filling up the whole building with its train.  The angels flitting about and singing a thunderous song that shook the foundations of this great building.  You might think Isaiah would leap for joy to see such a sight.  But that is not his reaction.

He realizes this is his doom.  For as much as God is, as the angels sing, “holy, holy, holy”, Isaiah is “sinful, sinful, sinful.”  He immediately becomes acutely aware of his own sin, his own unworthiness, especially to stand in the presence of Yahweh, that his eyes have beheld such a sight.  And dread seizes him.

“I am a man of unclean lips, and I live in the midst of a people of unclean lips.”  Isaiah is caught in his lie, and it’s a big one.  There’s no talking your way out of this one.  Isaiah knew it well. 

We can sympathize.  At least, we should.  For we too are people of unclean lips.  From the same mouth pour blessings and curses, and this should not be!  From our lips come all sorts of lies and deceits, disparaging of neighbor and prideful boasting.  We do not speak well of our neighbor as we should.  We do not defend his reputation as we ought.  We find countless and creative ways to sin with our lips, our words, and our failures to speak as we ought. 

Unclean lips.  That’s just scratching the surface.  Our whole lives are a lie.  We live day to day as if we aren’t unclean – putting on a show for ourselves and others that everything is just fine and we’ve got it all together and life is good.  Sometimes the truth peeks through here and there.  But Isaiah’s vision tears back the curtain, rips off the façade, and lays bare the truth for him – and for us – we’re doomed.  Woe is me!  Woe is you, too, fellow sinner.  Woe is us all.

One thing Isaiah’s lips do get right, however, is to confess this miserable situation.  He rightly speaks when he admits and owns his uncleanness.  As do we.  Confessing our sins is one of the best things we can do with these unclean lips.  A bit of honesty about ourselves prompted and moved by the Holy Spirit, who convicts our unclean hearts by his law.  Then, when we are brought low, when faced with the stark reality of it, how dire our sinful situation is, we are ready for cleansing, for grace, for restoration, for atonement.

As holy, holy, holy as he is, God is also merciful, merciful, merciful.  He doesn’t let Isaiah languish long in his guilt, but he sends forth one of these holy angels to perform an important task.  A glowing coal from the altar, the place of sacrifice, is taken and touched to Isaiah’s lips.  And the angel speaks the good news:  “This has touched your lips.  You sin is atoned for.”  The thunderous voice that shook the doorposts now speaks a kind and gentle word of pardon.  And it came so swiftly, so fully, and so freely.  God is merciful.

That altar is the place of sacrifice, and it is a shadow itself of the great sacrifice to come.  The Lord who sits enthroned above the temple would himself come down and assume our human flesh, take on our unclean lips and hands and hearts, and carry them with all their sin and guilt to his cross.  There, at the cross, atonement is made for Isaiah, for all his people, and for all people of unclean lips, even those here today.  The fire of God’s wrath consumes Christ, and not us.  The woe that was us, he faces in our place.  The just sentence of death that should have been upon us, falls upon him, and he bears it graciously.

In many and various ways God spoke to our fathers of old.  In burning bush and fiery pillar, in cloud and smoke and awe.  In dreams and visions, like this one seen by Isaiah.  But now in these last days he has spoken to us by his Son.  Jesus has come.  And we have his word.  We have preachers who bring that good news to us, much as the angel did for Isaiah.  But we have even better.

In the vision, God forgave Isaiah with the glowing hot coal that touched his lips.  But in these last days, he forgives us also by means of the Sacrament.  Here, he touches our lips with bread and wine that deliver us Christ’s body and blood, and our sin is atoned for.  Here, the holy, holy, holy One makes us holy by the forgiveness of our sins. Here the “woe is me” becomes, “how greatly blessed I am!”

But that’s not the end of the story, either.  Isaiah, now forgiven and at peace, is given an opportunity to serve.  “Whom shall I send?” God asks, and Isaiah responds in faith, “Here am I!  Send me.” No more is he wallowing in woe, paralyzed by fear of judgment.  The forgiveness of God empowers and frees us to serve.

It wasn’t going to be a picnic.  God was sending Isaiah as a prophet to a people unwilling to listen.  But just as Isaiah couldn’t have cleansed himself, but God provided for him, so does he also equip people for service that they couldn’t otherwise imagine they could do.

See also our Gospel reading, where Jesus similarly calls his disciples to leave their nets behind and become “fishers of men.”  Surely they had no idea what was to come.  But they trusted the one who called them, and he was faithful.

God has forgiven you, in Christ.  Your sin is atoned for.  And you, too, are called to serve.  You may not be called to the divinely instituted office of the public ministry.  But you may be called to serve as father or mother, wife or husband, son or daughter, teacher or student, employee or employer, citizen or friend. 

Wherever God has placed you, whomever he has placed in your care, however he has called you to serve, do so in the courage and confidence of a Christian.  Your lips and hands and hearts are clean in Jesus Christ, the once-and-for-all sacrifice.  When God comes calling, “whom shall I send?”, join your voice to Isaiah’s and cry, “Here am I!  Send me!”

In Jesus’ Name, Amen.
