Zechariah ministered to the restoration community to motivate those Jews to finish rebuilding the temple and to rededicate themselves to Yahweh with the prospect of His blessing. The central theme of the book is encouragement and hope.9The key to this hope is the coming of Messiah and his overthrow of ungodly forces and establishment of His kingdom on earth.
"The prophet is concerned to comfort his discouraged and pessimistic compatriots, who are in the process of rebuilding their Temple and restructuring their community but who view their efforts as making little difference in the present and offering no hope for the future."10
This prophet dealt with the future of Israel, and particularly its distant, eschatological future, to an extent that surpassed the other Old Testament prophets (cf. 12:1-3, 9; 14:1-5, 16-21). His revelations concerning the day of the Lord are numerous.
"What former prophets revealed at length, Zechariah epitomizes for us in terse sentences or even clauses."11
This book also contains many messianic prophecies (cf. 3:8-9; 6:12-13; 9:9-10, 14; 11:12-13; 13:7; 14:4, 9, 16).
"Particularly prominent in the book is the Messianic element. With the exception of Isaiah, there is no other prophet whose book contains such a wealth and variety of this element, not only in proportion to the total amount of material offered, but also as a sum total of passages."12
"Few books of the OT are as difficult of interpretation as the Book of Zechariah; no other book is as Messianic."13
