We preach a Gospel of light

Sermon for midweek of Transfiguration

Matthew 11:25-27  +  2 Corinthians 4:5-6

This week of the Transfiguration, we’re still focused on the glory of Christ that is real, but that is hidden from the world. It’s hidden from our eyes, too, so that we can’t see it. But our joy as Christians is that God the Holy Spirit has revealed Christ’s glory to us, so that we believe it is real, so that we see it with the eyes of faith. He has enlightened us with the Gospel so that we believe that Jesus is true God and true Man, and also believe in Jesus, the God-Man, as the One who speaks the truth to us and saves us from wrath and condemnation by the power of His blood shed on the cross.

Tonight, with Jesus and with the Apostle Paul, we have to take a step back and simply say a prayer of thanks to God for giving us this light, and by light I mean knowledge, and by knowledge, I mean both the knowledge of Christ and the confidence that goes with it, which we call faith. And not just to us here, but to all true Christians who hear the preaching of the Gospel and believe in Christ Jesus as a result. Because that faith-knowledge is and always has been hidden from most—hidden, as Jesus says, from the wise and the prudent. Hidden, or “veiled,” as St. Paul writes just a few verses before the ones you heard tonight, veiled to those who are perishing, whose minds the god of this age has blinded, who do not believe, lest the light of the gospel of the glory of Christ, who is the image of God, should shine on them.

It’s not that we have some secret knowledge that we’re unwilling to share with “certain people,” like the lodges or the secret societies of the world claim to have. No, as Paul writes to the Corinthians, our preaching is like a bright light, unmistakable, not hidden at all. And we don’t shine that light on ourselves. We do not preach ourselves, Paul says. Ministers—true ministers of Christ—don’t highlight their own accomplishments. No, Paul writes, we preach Jesus Christ as Lord. We preach about Christ Jesus plainly and openly—that He is the Lord, the Son of God and the same God proclaimed in the Old Testament who came into the world and took on human flesh to take away the sin that we have done.

Our sin is exposed by a different kind of light, the light of God’s holy Law, that is, His commandments, which tell us what is right and wrong in His sight, commanding us to do the right and avoid the wrong, but also accusing us of doing just the opposite in many cases. Now, whatever the details are of your disobedience to God’s commandments, the Law reveals that you are sinful, and, therefore, unable to escape from the Law’s just condemnation. You’ve earned God’s wrath for yourself, and a place in hell. All people have. That’s what the Law preaches.

But the light of the Gospel is also revealed through preaching. It shines forth from a God who is good and merciful, who gave His Son to be punished for the evil you have done. The light of the Gospel shines from Christ, who is good and merciful, and who bore your sins in His body. The light of the Gospel lights up the mercy of God in the face of Christ and shows you where to find the mercy and the forgiveness that you so desperately need: in the ministry of the Word of Christ and the Sacraments of Christ. God the Holy Spirit is active in the preaching of the Gospel, shining the light of Christ Jesus out into this room, where He is being preached, out into the world wherever His Gospel is preached, and penetrating the darkness of men’s hearts with that light, just as He once penetrated the darkness of the universe with His command, “Let there be light!” So He has shone in our hearts, Paul says about himself and his fellow ministers, that we, in turn, might shine forth the light of the knowledge of the glory of God in the face of Jesus Christ.

Not everyone sees it. To them the Gospel is veiled. Their minds are blinded by Satan, the god of this age. They don’t believe in this merciful God. They pretend that Jesus doesn’t even exist, or they twist the real Jesus into someone else, someone who “gets us,” as the ad campaign falsely portrays him, instead of portraying Him rightly, as the God who died for our sins and rose again, and calls us to repentance, that we may sin no more.

So what should we do? Is it a matter of saying just the right words in order to convince them, in order to lift the veil from their hearts and to cure the blindness of their minds? Not at all. Jesus and His apostles spoke all the right words. The Gospel shone forth brightly from their mouths. And most still didn’t believe.

What we do, all that we’ve been given to do, is, we preach Christ Jesus the Lord. Ministers preach Him, and you laymen speak openly about Him and show by how you speak and how you live that Jesus is, indeed, your Lord. And God the Holy Spirit will enlighten whom He will enlighten. Through His Spirit, Jesus, the Son of God, will reveal the Father to whom He wills to reveal Him, as He said in the Gospel. As for you, to whom the Holy Spirit has revealed the light of Christ so that you believe in Him and confess Him, rejoice in God’s gracious election, and in God’s mercy to you, that you should hear the Gospel rightly preached and have the Sacraments rightly administered, and that you should believe the voice of the Gospel and see the light of the Gospel unveiled. And we ministers will continue to preach Christ Jesus the Lord, even as you Christians continue to live in the world as children of God, as children of light, and as the very lights that God has strategically placed into this dark world, that Christ may be honored, that the faithful may be preserved, and that your neighbor may be helped, and even eternally saved. Amen.
