The sermon is concerned with the rest of chapter 29. Its themes can divided up into three sections: God’s command about the length of the consecration ceremony; God’s command about the daily offerings; and a summary statement about God’s great purpose for the sanctuary. What we read here is God’s way of him graciously providing a way for him to dwell with Israel.
As Paul evangelized sinners and edified saints by preaching Christ crucified, he considered himself God’s fellow worker. In this text, we see the way he went about this in practice. The main point here is that Christian ministers must be faithful to the NT pattern of ministry. This is not only true for Christian ministers, but true for believers who serve the body of Christ with their gifts, for each of us have a responsibility to be making disciples through the word of God. This passage contains several lessons about the work of the Lord.
