Luke 3:6

Greek Key Terms:

• πᾶσα σὰρξ (pasa sarx) = "all flesh" - Universal humanity, emphasizing inclusion of Gentiles
• ὄψεται (opsetai) = "will see" - Future indicative, prophetic certainty; all humanity will behold God's salvation
• τὸ σωτήριον τοῦ θεοῦ (to sōtērion tou theou) = "the salvation of God" - Personified salvation (Christ himself); from Hebrew yeshu'at Elohim
• εὐθείας (eutheias) = "straight" - Paths made straight for the Lord's coming
• φάραγγες (pharanges) = "valleys" - Filled; obstacles to Messiah's coming removed
• ὄρη (orē) = "mountains" - Made low; barriers between God and humanity removed

Context: Luke quotes Isaiah 40:3-5, extending beyond the Synoptic parallels (Matthew 3:3, Mark 1:3) which stop at verse 3. Luke alone includes verse 5: "and all flesh shall see the salvation of God." This addition emphasizes Luke's universal gospel theme - salvation extends to all peoples, Jew and Gentile. John the Baptist prepares way for Messiah whose mission will encompass every nation, fulfilling Jonah's reluctant mission to Nineveh on global scale.

Connections:

• TO:
• Isaiah 40:3-5 - original prophecy); Simeon's prophecy that Jesus would be "light to lighten the Gentiles" (Luke 2:31-32, quoting Isaiah 49:6); Abraham's promise of blessing to all families (Genesis 12:3); Servant bringing salvation to earth's ends (Isaiah 49:6
• FROM OT:
• Isaiah's vision of all nations seeing God's glory (Isaiah 66:18-19); Valleys raised, mountains lowered as metaphor for removing barriers to Gentile inclusion (Isaiah 40:4)
• FROM NT:
• Great Commission to all nations (Luke 24:47 - "repentance and forgiveness proclaimed in his name to all nations"
• Acts 1:8 - "ends of earth"); Paul's Gentile mission (Acts 13:47, Romans 10:12-13); Universal salvation offer (Acts 10:34-35

Connection Method(s): Promise-Fulfillment, Longitudinal Theme — Luke's extension of the Isaiah 40 quotation to include "all flesh shall see the salvation of God" fulfills the prophetic promise of universal salvation, advancing the longitudinal theme of Gentile inclusion from Jonah's reluctant mission to Christ's universal gospel.

Christological Connection: John the Baptist prepares the way for the One whose salvation will extend to "all flesh" - every tribe, tongue, and nation. This is Jesus Christ, the incarnate "salvation of God" (Luke 2:30, 3:6). Where Jonah reluctantly brought God's word to one Gentile city, Christ eagerly embraces mission to all peoples. The "level highway" represents removal of the dividing wall between Jew and Gentile (Ephesians 2:14) accomplished through Christ's cross. No longer are mountains (barriers of law, ethnicity, ritual) preventing Gentiles from accessing salvation. "All flesh will see" finds fulfillment in Christ's ministry: he touches lepers, eats with sinners, heals Gentiles (centurion's servant, Syrophoenician's daughter), commissions disciples to "all nations" (Luke 24:47), and sends Spirit on "all flesh" at Pentecost (Acts 2:17, quoting Joel 2:28). The Baptist's prophecy reaches climax in Revelation's vision: "every eye will see him" (Revelation 1:7), and multitude from every nation worships the Lamb (Revelation 7:9). Christ is the salvation that all flesh sees - not just Jewish remnant, but Gentiles from earth's ends, fulfilling Jonah's mission infinitely beyond what the reluctant prophet accomplished at Nineveh.
