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.
The purpose of the consecration is that Aaron and his sons may serve me as priests. If you are going to be in God’s tent, in the tent of the King of all the earth, in the Creator who dwelt in holy Eden, you must first be holy. This ceremony will consecrate these men for such a significant task in the symbolic and representative way that god reveals here in these verses. The intention this morning is first to explain the ordination of the priests so that we understand what is going on here, and then draw out the most significant parts of this revelation for our edification.
