The Altar of Incense

And thou shalt make an altar to burn incense upon: of shittim wood shalt thou make it. There are two altars, the brazen altar of burnt offering and the golden altar of incense. They are both typical of the work and person of the Lord Jesus Christ, but in distinct aspects.
At the brazen altar, we see Christ in death and resurrection, offering himself without spot to God, and accepted in all the sweet savor of his perfect sacrifice. The ground of the believer’s acceptance and communion with God.
At the golden altar, we see Christ in resurrection life and ascended glory, in all the excellency of his character and ways before God, through whom the children of God draw near and worship with confidence and joy.
Both the brazen and the golden altar were made of shittim wood within, as showing that the incarnation of Christ lies at the foundation of his whole work on behalf of his people; for the children being partakers of flesh and blood, he himself likewise took part of the same.
