Faith Is Measured by What We Do

Matthew places Jesus in the temple during the last week of his earthly life, right after he has turned over the money changers’ tables and called out a house of prayer made into a den of robbers. The chief priests and elders come with a question that sounds proper but carries a trap: “By what authority are you doing these things?” Their question is really, “Who do you think you are?” Their credentials are human credentials, and they want Jesus either to admit he has none or to claim God sent him and give them a charge of blasphemy.

Jesus turns the trap right back around. John the Baptist becomes the test case: did his authority come from heaven or from human beings? The religious leaders cannot answer honestly because they did not receive John, yet they fear the crowds who did. Their “we do not know” reveals that protecting their position matters more than recognizing God at work.

Jesus then makes the issue plain through two sons. The first son says no but later goes into the vineyard. The second son says, “I go, sir,” but never moves. The first son does the father’s will, not because his first words were good, but because his feet finally followed. Faith is not measured only by correct answers, clean doctrine, polished worship, or religious vocabulary. Faith gets measured in a life that actually goes into the vineyard.

The tax collectors and prostitutes expose the painful irony. Their lives may have begun with a loud no, but they believed John and changed their minds. The religious leaders had all the right words and saw the evidence in front of them, but still would not change. Jesus warns that it is possible to spend an entire life in the batting cages and never play the game, study the cookbook and never prepare a meal, or memorize the lines and never let the curtain rise.

Prayer to the living God cannot leave a person indifferent to suffering people. The cold child in the tent makes clear that devotion which will not give away a sweater has become devotion to “a pole, a shade,” rather than to God. Worship inside the sanctuary must spill into life outside it. God does not need salt kept safely in a bag on Sunday morning. God wants salt scattered everywhere it goes, and God wants people who know the song to actually sing it with transformed lives.

Key Takeaways

• 1. Doing reveals what belief truly is Jesus makes the first son the faithful one because he finally goes to work in the vineyard. Correct speech matters, but it cannot substitute for obedience when the Father has given a clear command. A life can sound deeply religious while quietly refusing the very work God asks it to do. [44:25]
• 2. Authority recognizes God at work The chief priests and elders possess the official credentials, yet their fear keeps them from answering truthfully about John. Their problem is not lack of information but unwillingness to surrender control when God acts outside their approved channels. Religious authority becomes dangerous when protecting status matters more than receiving truth. [41:22]
• 3. Repentance changes direction, not merely language The tax collectors and prostitutes enter ahead because they believe and change their minds. Their former no does not have the final word when repentance turns their lives toward God. The leaders’ apparent yes becomes empty because they see the evidence and still refuse to move. [30:47]
• 4. Prayer must touch suffering bodies The freezing child exposes the false comfort of spiritual activity detached from mercy. Prayer before the living God presses a person back into the world with open hands, a sweater, and a willingness to bear another’s need. Indifference to suffering makes devotion hollow, no matter how sincere its words may sound. [47:23]
• 5. God wants salt scattered, not stored Church can become a place for getting every note right while missing the reason for singing. God desires transformed lives that carry the flavor of Christ into ordinary places and wounded situations. Salt fulfills its purpose only when it leaves the bag.

Bible Reading

Matthew 21:28-32
“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 go, 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.” [30:19]

Matthew 21:23-27
“And when he 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 will also 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.” [28:45]

Matthew 5:13
“You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people's feet.” [52:32]

Observation questions

1. What two actions by Jesus led the chief priests and elders to question his authority in the temple? [36:05]
2. What reasons did the religious leaders give themselves for refusing to answer Jesus’ question about John the Baptist? [41:22]
3. How do the two sons respond differently to their father’s request, and which son is identified as doing the father’s will? [43:01]
4. What contrast does Jesus draw between the religious leaders and the tax collectors and prostitutes in their response to John’s message? [30:49]

Interpretation questions

1. Why does Jesus make John the Baptist’s authority the test case for answering the leaders’ question about his own authority? What does their refusal to answer reveal about what they value? [41:13]
2. The second son gives a respectful answer but does not go to the vineyard. What kinds of religious words or habits can sound faithful while avoiding actual obedience? [44:25]
3. Why is changing one’s mind and acting differently such an important sign of repentance in this passage? How does this give hope to people whose lives may have begun with a strong “no” to God? [30:57]
4. How does Jesus’ image of salt scattered into the world help explain the connection between worship, faith, and daily life? [52:18]

Application questions

1. Is there an area where it is easy to say, “I go, sir,” but difficult to actually take the next obedient step—perhaps in forgiveness, generosity, service, honesty, or reconciliation? What might “going into the vineyard” look like this week? [44:25]
2. When have concern for reputation, comfort, or approval made it harder to recognize or respond to something God may be asking? What would honest repentance look like in that situation? [42:05]
3. The first son’s initial refusal was not the end of his story. Where might God be inviting a changed mind and a changed direction rather than shame or pretending? [43:53]
4. Think about a suffering person or practical need that is already close at hand. What is one concrete way this group or its members could respond with more than concern or prayer alone? [47:37]
5. In what settings outside church—home, work, school, neighborhood, or online—does faith need to become “salt” that brings Christ’s character into the world? What specific action could make that visible? [52:32]
6. What practices help keep Bible knowledge, worship, and prayer connected to a life that actually follows Jesus rather than merely knowing the right words? [50:07]
