What does the brazen altar represent about Christ?
The brazen altar represents Christ as the sacrifice, prefiguring His finished work at the cross. It speaks of His death and propitiation, fulfilling everything the altar symbolized. The tabernacle elements picture Christ, and the altar specifically points to His sacrificial offering for sin.
Les explains that every element of the tabernacle and its court, from the gold and silver to the wood and brass, is a picture of Christ's finished work. He became our sacrifice at the cross and fulfilled everything that the brazen altar could ever speak of. That work is propitiation, and Scripture shows His death was potentially enough for every human being brought into the scene.
