And when [Jesus] entered the temple, the chief priests and the elders of the people came up to him as he was teaching, and said, “By what authority are you doing these things, and who gave you this authority?” Jesus answered them, “I also will ask you one question, and if you tell me the answer, then I also will tell you by what authority I do these things. The baptism of John, from where did it come? From heaven or from man?” And they discussed it among themselves, saying, “If we say, ‘From heaven,’ he will say to us, ‘Why then did you not believe him?’ But if we say, ‘From man,’ we are afraid of the crowd, for they all hold that John was a prophet.” So they answered Jesus, “We do not know.” And he said to them, “Neither will I tell you by what authority I do these things. What do you think? A man had two sons. And he went to the first and said, ‘Son, go and work in the vineyard today.’ And he answered, ‘I will not,’ but afterward he changed his mind and went. And he went to the other son and said the same. And he answered, ‘I will, sir,’ but did not go. Which of the two did the will of his father?” They said, “The first.” Jesus said to them, “Truly, I say to you, the tax collectors and the prostitutes go into the kingdom of God before you. For John came to you in the way of righteousness, and you did not believe him, but the tax collectors and the prostitutes believed him. And even when you saw it, you did not afterward change your minds and believe him.”
Matthew 21:23–32, ESV
Grace and peace to you from our Lord and Savior, Jesus Christ. Amen.
Authority. Who has it? Where does it come from? That’s what the Chief Priests and Elders wanted to know.
Who gave you the right?
Only days before Jesus had entered Jerusalem as King. The people spread palm branches in front of him. He rode on a donkey, fulfilling the scriptures. He drove the buyers and sellers out of the temple.
It is written, ‘My house shall be called a house of prayer,’ but you make it a den of robbers.
Matthew 21:13, ESV
It wasn’t a pretty sight. Jesus turning over tables. Then calmly he returns to teach.
By what authority are you doing these things? They ask.
Seems like a reasonable question.
But they aren’t asking in honesty seeking the truth. They don’t want to know about Jesus. They are challenging his right to interfere with their authority, their worship, their place in their communities. Their whole lives.
You and I might ask the same question of God’s Word. There are things that we want to protect.
- Who gives it authority to command forgiveness when I have been wronged?
- Who gives it authority to call my sexual desires sinful?
- Who gives it authority to forgive people whom I do not think deserve forgiveness?
We ask these questions; we don’t always reject Christ and his Word openly. Sometimes we hide it in questions and excuses.
Chief Priests and Elders wanted to know. They calculate instead of confessing. They ask the question,
Who gives you the authority…
Jesus is patient. He asks a defining question.
Did John’s baptism come from heaven or from man?
They don’t consider if either answer is true. What they do is calculate what each answer will cost them. If they say, “from heaven,” Jesus will ask why they did not believe John. If they say, “from man,” they fear the crowd. “We do not know” is not uncertainty. It is calculated evasion.
We manage our issues the same way. We wonder what we can safely admit. We avoid the question of what God has said. We are worried about appearances in the eyes of other people. We want to avoid embarrassment. We fear that more than unbelief. We defend instead of confess.
But repentance is the end of managing appearances before God.
When we listen to Jesus’ parable about the two sons, we try to push ourselves into who did better. The first son openly refused his father but later changed his mind. The second respectfully says he will go but never does. One son rebels against his father with his mouth. The other rebels beneath obedient words. Both sons reveal things about us.
That’s us. Sometimes we simply say no to God. Other times we have the right words, religious words about trusting or obeying. Church membership, theological vocabulary, offices, and years of service cannot substitute for faith.
Jesus didn’t praise the tax collectors and prostitutes for their sin. They entered because they believed John’s word. They repented. Respectable unbelief remains unbelief.
So, who actually did the father’s will? The first. He initially refused but repented and went anyway. Jesus’ parable shows us our sin. We sometimes openly refuse then do what God asks anyway. At the same time, we sometimes say the right thing but don’t follow through. Neither of those responses is perfect obedience to God’s will. Neither son obeyed perfectly.
But there is One Son who does the Father’s will perfectly.
He is standing there in the temple confronting sin and preaching the truth. It is Jesus.
Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.”
Philippians 2:5–11, ESV
Jesus possesses God’s authority, but he doesn’t use it as we would. He doesn’t use it to protect himself. He comes with authority in the form of a servant. To serve you and me. He humbles himself. He obeys God’s will even though it meant his brutal death on the cross.
You and I have said no and disobeyed. We have said yes and failed to go. Jesus says yes to His Father and went all the way to the cross. We are openly rebellious and outwardly respectable. We deserve the judgment of God’s Word. But Jesus received the judgment instead of us. He hangs on the cross in our place. He fulfills God’s Word perfectly, completing the Father’s saving will for us.
The real question isn’t just “Who gave Jesus this authority?” It is also, “What did Jesus do with it?” Receive Jesus’ righteousness. He went to the cross for you. It is yours through faith.
That same authority does even more. In Baptism, the Lord places His name upon sinners. In Absolution, Christ authoritatively forgives what we can no longer excuse. In Scripture, He calls us out of evasions and into faith. In the Supper, the exalted Lord still stoops down to give His body and blood for forgiveness.
Jesus said to them, “Truly, I say to you, the tax collectors and the prostitutes go into the kingdom of God before you. For John came to you in the way of righteousness, and you did not believe him, but the tax collectors and the prostitutes believed him.”
Jesus is mercy. His warnings come with a summons. Believe! Stop protecting the appearance of righteousness. Stop defending your refusal to do what he commands. Believe the Word of God. Receive Jesus’ righteousness that sent him to the cross for you. It is yours through faith.
“Who gave Jesus the right?”
His Father did. He is the eternal Son and risen Lord.
But see what He does with that right: He places Himself beneath sinners, bears their judgment, and opens His kingdom to them.
Jesus has the authority to expose your sin.
And Jesus has the authority to forgive it.
Amen.
The peace of God that passes all understanding keep your hearts and minds in Christ Jesus. Amen.
