Zechariah is an unlikely hero because he wrestles with doubt. Even as he stands before the altar of the Lord, he cannot grasp God’s power. He cannot believe that God would do the miraculous, or that God would involve him and his wife in this way. And so he is unable to speak for a time. All Christians struggle with doubt at times over how God could use us in his redemption story. Yet God gives us evidence that He is ultimately in control.
