Original context
Isaiah 40 announces comfort for Jerusalem and a prepared way through the wilderness. The surrounding language concerns God's coming, the end of suffering and care for the people. The USCCB notes connect the image with the return of exiles from Babylon.
How the New Testament uses it
The Gospels apply the wilderness voice to John the Baptist preparing for Jesus. Mark's opening scriptural introduction combines material, so its wording should not all be attributed to Isaiah 40 alone. Luke quotes a longer portion of the Isaiah passage.
The Christian understanding
John's ministry is understood as preparation for God's saving action in Jesus.
Other readings and questions
The earlier text can be read as consolation and restoration for its own audience. The Gospel application can then be studied as a later theological reuse of a restoration promise.
What the connection can establish
The quotation establishes how the evangelists frame John and Jesus. Its historical and theological force depends on further judgments about the earlier promise, the ministry described and the connection between them.
