The temple references in Haggai relate to the following five theological themes: God’s sovereignty over redemptive history, God’s presence, the Edenic blessing, the new creation, and the Messianic kingdom. Haggai’s rebuilding of the temple provided the way for Jesus Christ’s first advent, and served as the starting point of the 70-week prophecy and the 2300-day prophecy, which concern the temple or the sanctuary. Jesus Christ is the Gospel itself, the temple-related themes provide biblical bases for mission and serve as guides for church leaders as they seek to establish practical mission projects. Suggestions for mission strategies are listed under each theme. Some of these suggestions come from the writer’s experience with the work of Global Welfare Supporters and Maha Mission in the East Central Africa Division of the Seventh-day Adventist Church.
