How did Christ fulfill the brazen altar?
Christ fulfilled the brazen altar by becoming our sacrifice at the cross, satisfying all that the altar prefigured. He also became our labor of cleansing, and His Word reveals our need while cleansing us, completing the picture of His finished work.
Les explains that the brazen altar was part of the tabernacle court that pictured Christ's finished work. Christ fulfilled it by becoming our sacrifice at the cross, meeting everything the altar could ever speak of. He also became our labor of cleansing, and His Word shows us our need as well as cleanses us. This fits the broader truth of propitiation, where every element of the tabernacle—from the outer court to the mercy seat—pictures Christ's finished work.
