Zechariah opens his book with an invitation: Return to God. His summons home depicts God as merciful, compassionate, and longsuffering. The portrait frames the remainder of the book, full of visions and oracles. From the outset, Zechariah sees God on the move. His protection is real: he patrols the earth. His promises will prevail: he will rebuild Jerusalem. Thus, God's reliability and activity should inspire his people to get unstuck and make a move.
