Luke 3:4

Preparing the Way

as it is written in the book of the words of Isaiah the prophet: “A voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for Him. Luke 3:4 · Berean Standard Bible

What It Means

Luke 3:4, in plain English

This was exactly what the prophet Isaiah had written about centuries earlier: 'A voice calling out in the wilderness: Get the road ready for the Lord! Make His paths straight!'

Why it's here

Isaiah wrote these words over 700 years before John was born. John's ministry was no accident—it was planned by God long before it happened.

Who's speaking

Luke connects John's ministry to Isaiah's ancient prophecy.

Where it sits in the story

Isaiah saw it coming from seven centuries away. A voice in the desert, calling people to prepare for God's arrival. That voice turned out to be John, and the road he prepared led straight to Jesus.

A Closer Look

The scholarly reading

Luke cites Isaiah 40:3 to identify John as the prophesied voice (phōnē) crying in the wilderness, preparing the Lord's way and making His paths straight. This fulfillment citation grounds John's ministry in prophetic authority.

Language and setting

All four Gospels quote this Isaiah passage for John, but Luke uniquely extends the quotation through Isaiah 40:5, including the universal scope of salvation.

Voice

Luke provides the scriptural basis for John's ministry by quoting Isaiah.

Significance

Seven centuries before John was born, Isaiah described a voice in the wilderness preparing the way for God. Luke identifies John as that voice, connecting ancient prophecy to present fulfillment.

In context

Luke 3:2–6

2during the high priesthood of Annas and Caiaphas, the word of God came to John son of Zechariah in the wilderness.

3He went into all the region around the Jordan, preaching a baptism of repentance for the forgiveness of sins,

4as it is written in the book of the words of Isaiah the prophet: “A voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for Him.

5Every valley shall be filled in, and every mountain and hill made low. The crooked ways shall be made straight, and the rough ways smooth.

6And all humanity will see God’s salvation.’”

Read all of Luke 3 — John the Baptist doesn't just call for repentance — he gets specific. Tax collectors, soldiers, and crowds all hear what it costs to change.
