An Overview of the Gospel of Luke

Why Luke Matters—And What It Means for Us

“The Certainty We Need in a World of Questions”

We live in an age of information overload, yet many believers still wrestle with uncertainty when it comes to their faith. That’s why Luke’s Gospel is such a gift. Written by a doctor—not an apostle, not a celebrity preacher, but a humble, detail-loving physician—it offers something precious: a faith you can be sure of.

Luke carefully investigated everything. He didn’t see Jesus in person, but he listened, researched, and compiled an account so trustworthy it has encouraged generations of Christians—including a man named Theophilus, and now, us.

His message is clear: Jesus isn’t just a figure from history. He’s the Son of Man—the one who stepped into our world, full of compassion for the outcast, the forgotten, and the sinner. And He didn’t just teach; He came to seek and save the lost.

That includes you and me.

Luke’s Gospel is personal. It reminds us that God can use anyone—Luke, Theophilus, you, and me—to further His mission. You don’t need a title. You don’t need a spotlight. You just need a heart that says, “Yes, Lord.”

So as we begin this journey through Luke, let’s ask ourselves:
Are we certain of what we believe?
Are we growing in our love for Christ?
Are we willing to be used by Him?

Because the story Luke tells isn’t just about what happened then. It’s about what God wants to do in us now.

Main Idea:

This sermon launches a new series in the Gospel of Luke by laying the foundation—explaining the genre, authorship, purpose, themes, structure, and distinctives of the book. Luke, a Gentile physician and companion of Paul, wrote both the Gospel of Luke and the book of Acts. His gospel focuses on Jesus as the Son of Man and is addressed to Theophilus with the goal of strengthening believers’ confidence in the truth about Jesus.

Key Points:

• Literary Context: Luke is one of the four Gospels, the longest book in the New Testament by word count, and part of the narrative section of Scripture.
• Author: Luke was a physician, Gentile, and close companion of the Apostle Paul. He was not an eyewitness but carefully investigated the life of Jesus.
• Audience: Theophilus (likely a Gentile official) and a broader Gentile readership.
• Purpose: To give believers certainty about what they’ve been taught (Luke 1:1–4).
• Theme: Jesus as the Son of Man—a title that expresses both His humanity and deity.
• Distinctives:
  • High Gentile appeal; fewer OT references.
  • Emphasizes the outcasts, women, children, sinners, and Gentiles.
  • Nearly 50% of its content is unique, including many parables.
  • Medical details consistent with Luke’s profession.
• Structure: The longest section (chapters 9–19) highlights Jesus’ determined journey to the cross in Jerusalem.
• Takeaway: Knowing the truth with certainty, in an organized way, deepens our love and commitment to Christ.
