Saint Luke’s Gospel: Certainty in Christ’s Saving Word

Saint Luke begins his holy gospel with a promise of certainty. His orderly account rests on careful attention to the events fulfilled among God’s people and the testimony of eyewitnesses who were there from the beginning. His gospel is not a collection of cleverly designed myths. Every detail belongs to an accurate and true account of Jesus Christ, so that those who have been taught the faith can know what they have believed is the truth.

Luke’s two volumes trace the work of the same Lord. His gospel follows Jesus through his birth, life, suffering, death, and resurrection, right up to his ascension. The Acts of the Apostles then records how the risen Lord continues his work through the early church, including the journeys of that blasphemer turned missionary, Saint Paul.

Jesus sends out the seventy-two with sobering words: “The harvest is plentiful, but the laborers are few.” His picture of lambs in the midst of wolves leaves no room for pretending that the world welcomes his kingdom. Sin has set the world against God since Adam and Eve fell in the garden. That rebellion remains visible in violence, in the rejection of God’s good and holy laws, and in the sin residing within every human heart.

False doctrine brings that hostility into places claiming to speak for God. The denial of Jesus as Lord and Savior and the treatment of Scripture as material to be corrected stand directly against Luke’s assurance. Such voices are wolves in sheep’s clothing, drawing people away from the truth.

God’s Word answers that darkness with Jesus Christ crucified for sinners. The Scriptures, from Genesis to Revelation, are not fairy tales or fables. The Holy Spirit has given these words to make sinners wise to salvation in Christ Jesus. This Word is sweeter than honey and a lamp in the darkness.

Christ stands at the center of it all. His holy, precious blood and innocent suffering and death redeem sinners from sin, death, and the power of the devil. His resurrection gives the assurance of new life. The same Spirit who guided Luke gives faith through the Word and is bestowed in holy baptism, opening ears to hear the good news. Saint Luke deserves remembrance because his faithful account points away from himself to the Savior who is worthy of all praise.

  * Christ sends lambs into real danger.
  
  Christ’s picture of lambs among wolves names the hostility surrounding the proclamation of his kingdom. That warning exposes both open rebellion against God and religious voices that deny his Word. The need for the gospel remains urgent because sin resides not only in the surrounding world but within every human heart.
  
  * Scripture’s center is the crucified Christ.
  
  God’s Word does more than expose the world’s errors. Its light reveals Jesus Christ crucified for the forgiveness of sins and raised to give new life. The certainty of Scripture therefore serves the certainty of salvation, directing faith toward Christ’s finished work rather than human judgment.
  
  * The same Spirit opens closed ears.
  
  The Holy Spirit who guided the prophets and evangelists also brings sinners to hear and believe their words. His gift in holy baptism joins the written account of salvation to the believer’s reception of Christ’s benefits. Christ’s holy, precious blood, not gold or silver, establishes the redeemed sinner’s place in his eternal kingdom. [30:47]

Bible Reading

Luke 10:1-3
“After this the Lord appointed seventy-two others and sent them on ahead of him, two by two, into every town and place where he himself was about to go. And he said to them, “The harvest is plentiful, but the laborers are few. Therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest. Go your way; behold, I am sending you out as lambs in the midst of wolves.” [24:47]

Luke 1:1-4
“Inasmuch as many have undertaken to compile a narrative of the things that have been accomplished among us, just as those who from the beginning were eyewitnesses and ministers of the word have delivered them to us, it seemed good to me also, having followed all things closely for some time past, to write an orderly account for you, most excellent Theophilus, that you may have certainty concerning the things you have been taught.” [29:57]

2 Timothy 3:16
“All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness,” [36:12]

Observation questions

1. In Luke 1:1–4, what sources and careful steps does Luke identify in preparing his account? What does he want that account to give his reader? [30:03]
2. In Luke 10:1–3, what do Jesus’ pictures of the harvest and of lambs among wolves reveal about the task facing those he sends? [33:59]
3. What two kinds of opposition to God’s Word are identified—both in the surrounding world and among those claiming to speak for God? [35:40]
4. In connection with 2 Timothy 3:16, who is identified as the source of Scripture, and whose saving work stands at its center? [38:58]

Interpretation questions

1. Why does it matter for a Christian facing doubt that Luke records actual events supported by eyewitness testimony, rather than simply offering encouraging religious ideas? [30:49]
2. How does Jesus’ warning in Luke 10:1–3 prepare his followers for rejection without making the people they are sent to reach into enemies to be defeated? [34:10]
3. If Scripture is given by God, as 2 Timothy 3:16 teaches, how should a Christian approach a passage that challenges a deeply held opinion? How is seeking to understand different from deciding that Scripture needs correcting? [38:11]
4. Why must the recognition of false teaching and human sin lead toward Christ’s forgiveness rather than merely toward stronger arguments or better behavior? [40:16]

Application questions

1. When doubts about the Christian faith trouble you, where do you usually turn for reassurance? How might Luke’s careful account help you bring those doubts back to what Jesus has actually done? [41:31]
2. Is there someone with whom you hesitate to speak about Christ because you fear rejection? What might a gentle, honest conversation look like, and how could this group support you in prayer? [34:03]
3. It can be easier to recognize rebellion against God in the world than in our own hearts. Where have you noticed yourself resisting God’s Word, and how does Christ’s forgiveness help you confess that honestly? [34:43]
4. Think about the Christian messages you hear through podcasts, books, social media, or conversations. How do you test those messages against Scripture, and whom could you ask for help when something seems troubling or unclear? [38:11]
5. When guilt or failure weighs on you, what do you tend to rely on for peace? How could Christ’s death and resurrection—and the gift of the Holy Spirit in your baptism—give you firmer assurance than your feelings or performance? [40:36]
6. God’s Word gives light by pointing sinners to Christ. What realistic opportunity could you make this week to read Luke’s Gospel, and what might help you look for Christ’s saving work rather than only a lesson about improving yourself? [40:04]
