Just as Joseph was an integral person in the story of light, life, and love–so too was Zechariah. The parallels between the character of the two men is noticeable. They both practiced the better incarnationally.
Zechariah adds additional instruction to the picture in relation to the priesthood. Long before we see the conflicts between the religious leaders, expressed toward both John and Jesus, we are shown that there were priests who got it–who recognized what God was doing, and blessed what was happening. Zechariah was likely the first.
Specifically, the prophecy of Zechariah confirms the continuation of the covenant in all that was happening (Luke 1:72)–a continuation characterized by light, “the dawn from on high” that was breaking into time, giving “light to those sitting in darkness and in the shadow of death” (Luke 1:78-79). Like Joseph, Zechariah took his place as one who would practice the better and be a witness to light, life, and love. He did this for thirty years, until the time his son would move out to be God’s first prophet in four hundred years.
