True preachers make straight the Lord’s way

Sermon for Rorate Coeli – Advent 4

Philippians 4:4-7  +  John 1:19-28

Last week we met the preacher of preachers, John the Baptist, at the end of his ministry, in prison, sending his disciples to Jesus to ask Him if He was, in fact, the One who was to come. Today we go back in time a couple of years, to when John first began to preach and to baptize, before Jesus began His own ministry by being baptized by John. Who was this strange preacher, living out in the desert, wearing camel-skin clothing, eating a diet of locusts and wild honey, who came “neither eating nor drinking” at banquets or feasts, but led a solitary, ascetic life?

John tells us the most important thing about himself in today’s Gospel. Who was he? He was the preacher who made straight the Lord’s way, and in that way, he was the model for all preachers who would come after him.

If you recall, John had been making straight the way of the Lord since before he was born. When the newly pregnant virgin Mary greeted her relative Elizabeth, the baby John leaped for joy in Elizabeth’s womb, announcing to his mother that they were even then in the presence of the Lord.

Some thirty years later, John would leave his home and go out into the wilderness to continue preparing the Lord’s way. His strange lifestyle and his bold preaching began to draw people out to him from all over Israel, until large crowds were gathering around him on a regular basis to hear him. Many were also baptized by him. That got the attention of the religious leaders in Jerusalem. They were supposed to be in charge of the Church of Israel, but they had never sent John out to preach, and certainly not to baptize. So they sent a delegation out to him, to question him.

Who are you? they asked. And he confessed, and did not deny, but confessed, “I am not the Christ.” The Apostle John is careful to note John’s testimony, emphasizing his strong confession that he was not the Christ. He was not the one Israel was supposed to be waiting for or hoping in or trusting in.

Not the Christ…Then, are you Elijah? Nope. Not Elijah. The prophet Malachi had prophesied that Elijah would come ahead of the Lord, and according to Jesus, John was that Elijah. But he wasn’t the famous miracle-working prophet who was taken to heaven with a fiery chariot some 800 years earlier. That would have made John something supernatural and impressive. But he didn’t want or claim that kind of fame.

Are you the prophet? they asked, apparently referring to the prophet about whom Moses had prophesied: The LORD your God will raise up for you a Prophet like me from your midst, from your brethren. Him you shall hear. That was a reference to the Christ Himself, which they didn’t seem to understand. Nope, John said. I’m not the Prophet. In every way possible, John pointed away from himself, not seeking popularity, not seeking fame, not wanting at all to be the center of attention, except for the briefest moment, as people focus briefly on a road sign telling them which way to go, and then the sign has served its purpose and is quickly and appropriately left behind in the background.

John’s only desire was to be a sign like that. He told them, I am the voice of one crying out in the wilderness, ‘Make straight the way of the Lord,’ as the prophet Isaiah said.

There were three ways in which John did that “making straight the way.”

First, he preached repentance. He preached to the Jews, but we’re told that Roman soldiers also came to hear him. He told them what God’s holy Law demanded of them: obedience to the Ten Commandments, and he wasn’t afraid to point out that they had all gone astray, and where. He preached especially against adultery and sexual sins, against mistreating others, against stealing from others, against deceitful business practices. He exposed the people’s sin of putting their own interests first and taking advantage of one another. And he exposed the many ways they committed idolatry, not with idols of wood and stone anymore, but with idols of money, idols of flesh and blood, how they feared, loved, and trusted in themselves more than they feared, loved, or trusted in God. He warned them to repent, to recognize and to turn from their sins before God came against them in judgment. And so John made straight the Lord’s way, so that He might come with healing and forgiveness for the penitent.

Second, John baptized the penitent. Mark and Luke both describe John’s baptism as a baptism of repentance for the remission of sins. Those who confessed their sins, those who wanted God’s forgiveness and who wanted to amend their sinful lives, were invited to be baptized by John, to be baptized with water as a means by which God would wash away their sins and make them ready for Christ, who would actually take their sins on Himself and pay for them, eventually, on the cross.

Third, John pointed the people of Israel toward the Christ, who was already on the earth and was just about to reveal Himself. He said, There stands among you one whom you do not know. It is he who comes after me, who has been ahead of me, whose sandal straps I am not worthy to untie. Don’t look at me, John said. I’m only here for a moment to point you to Him. He is the great One. He is the Savior. He is the Lord. He is the One who remains forever and whose word does not pass away. He’s the One we’ve all been waiting for. Hope in Him. Trust in Him, and you will not be disappointed.

And so John has become a model for all the true Christians preachers who have come after him, so that he, through us, continues to make straight the Lord’s way in the hearts and lives of all who hear.

First, like John, true Christian preachers point away from themselves. They may make much of their ministry, as St. Paul also did, but they don’t make much of themselves. They don’t make much of their opinions, or their personal stories, or their degrees, or their charisma. They don’t seek the spotlight for themselves. Don’t look at me!

Second, like John, they preach repentance. They point out sin—the sin that dwells in your flesh and influences your every thought, word, and deed. They preach against obvious sins, and they preach against secret sins, including self-righteousness and hypocrisy. They warn you of God’s coming wrath against sinners. They urge you to “change your mind” about sin (that’s what the Greek word “repentance” actually means), to view it, no longer as something desirable or innocent, but as something ugly, harmful, and detestable.

Third, like John, true Christian preachers preach and administer Baptism. Baptism is God’s indescribable gift to mankind, where He invites penitent sinners to wash and to actually be made clean, to be forgiven for the sake of Christ, by being united with Christ in His death and in His resurrection. And now we also have that other great Sacrament, the Sacrament of the Altar, where Christ gives His body and blood with the bread and wine for the forgiveness of sins.

Finally, true Christian preachers, like John, are always found pointing to Jesus Christ, the One who came, true God and true Man, who suffered for you and died for you that you might live forever with Him. They point to Jesus Christ, the One who is now to be sought, not standing among you, not whispering in your ear, but speaking to you through the Word and ministering to you through the Office of the Holy Ministry. They point to Jesus Christ, the One who is coming again soon, the One whose Advent you should be expecting and longing for far more earnestly than any earthly success or relief.

So make straight the Lord’s way! He is the Savior. He is the Lord. He is the One who remains forever and whose word does not pass away. He’s the One we’ve all been waiting for. Hope in Him. Trust in Him, and you will not be disappointed. Amen.
