This altar was the place where the sinner approached God, in the power and efficacy of the blood of atonement. It stood "at the door of the tabernacle of the tent of the congregation," and on it all the blood was shed. It was composed of "shittim wood and brass." The wood was the same as that of the golden altar of incense: but the metal was different, and the reason of this difference is obvious. The altar of brass was the place where sin was dealt with according to the divine judgment concerning it. The altar of gold was the place from whence the precious fragrance of Christ's acceptableness ascended to the throne of God. The "shittim wood," as the figure of Christ's humanity, must be the same in each case; but in the brazen altar we see Christ meeting the fire of divine justice; in the golden altar we behold Him feeding the divine affections. At the former, the fire of divine wrath was quenched; at the latter, the fire of priestly worship is kindled. The soul delights to find Christ in both; but the altar of brass is what meets the need of a guilty conscience,--it is the very first thing for a poor, helpless, needy, convicted sinner. There cannot be settled peace, in reference to the question of sin, until the eye of faith rests on Christ as the antitype of the brazen altar. I must see my sin reduced to ashes in the pan of that altar ere I can enjoy rest of conscience in the presence of God. It is when I know, by faith in the record of God, that He Himself has dealt with my sin in the Person of Christ, at the brazen altar--that He has satisfied all His own righteous claims--that He has put away my sin out of His holy presence, so that it can never come back again--it is then, but not until then, that I can enjoy divine and everlasting peace. I would here offer a remark as to the real meaning of the "gold" and "brass" in the furniture of the tabernacle. "Gold" is the symbol of divine righteousness, or the divine nature in "the Man Christ Jesus." "Brass" is the symbol of righteousness, demanding judgment of sin, as in the brazen altar; or the judgment of uncleanness, as in the brazen laver. This will account for the fact that _inside_ the tent of the tabernacle all was gold,--the ark, the mercy-seat, the table, the candlestick, the altar of incense. All these were the symbols of the divine nature--the inherent personal excellence of the Lord Jesus Christ. On the other hand, _outside_ the tent of the tabernacle all was brass,--the brazen altar and its vessels, the laver and its foot. The claims of righteousness, as to sin and uncleanness, must be divinely met ere there can be any enjoyment of the precious mysteries of Christ's Person, as unfolded in the inner sanctuary of God. It is when I see all sin and all uncleanness perfectly judged and washed away that I can, as a priest, draw nigh and worship in the holy place, and enjoy the full display of all the beauty and excellency of the God-man, Christ Jesus.
