I just uploaded our overview and outline of Zechariah.
Zechariah was a contemporary of Haggai and began to prophesy before the last two prophecies of Haggai. He is known as an apocalyptic prophet in that he gives us a series of eight visions. Tim calls this book “The Prophecy of the Two Advents.” Both the first and second returns of Christ are prophesied of in this book.
The rest of the overview and outline of Zechariah is right here.
