Luke bases his Gospel on eyewitness testimony—the witness of those who saw and heard and knew Jesus as he lived and ministered among his people (Luke 1:2).

As we give careful attention to their stories, we too behold the coming of the Christ child, and rejoice with them at the wonder of God’s great salvation. To Zechariah, the promise of Christ’s coming demonstrates several qualities of our God (Luke 1:68–79).
