Quick answer

Zacharias asks for proof, citing his and Elizabeth's old age. He responds with doubt rather than faith.

Overview

Zacharias requests a sign because the promise seems impossible given their age. His question echoes Abraham's situation but reflects unbelief rather than trust. His doubt invites the discipline that follows and contrasts with Mary's later faith.

Christ at the center

Luke shows Jesus the Savior for all — outsiders, the poor, the nations — the one who, on the Emmaus road, opened all the Scriptures to show they were about himself.

How Luke 1:18 points to him is part of the one story that runs through all Scripture — meet Jesus at the heart of the web, or follow a trail that traces him from Genesis to Revelation.
