The House of the Lord: Three

The Altar of Burnt Offering was made of the same acacia wood found throughout the construction of the Tabernacle. In this case, the acacia wood was covered with bronze, the alloy of copper and tin, or perhaps with copper. The scholars are not certain. It seems likely from the account that it was one or the other.
The four horns sticking up from the four corners of the Altar symbolize the fact that the good news of Christ’s atoning death is to be preached to the ends of the earth; and that His death and the resulting atonement, working through the power of His resurrection, will push with irresistible power and authority until the Kingdom of God fills the earth and Christ is Lord of all.
During the days of the Tabernacle of the Congregation the four horns of the Altar of Burnt Offering were used for tying the animals to be sacrificed.
God is the Lord, which hath shewed us light: bind the sacrifice with cords, even unto the horns of the altar. (Psalms 118:27)
The Altar of Burnt Offering was quite large, about four and one-half feet high and seven and one-half feet square. The Altar dominated the Courtyard area as well as the countryside adjacent to the Tabernacle, because of the ceaseless activity of the priests, Levites, worshipers, animals; the sounds coming from it; and the smell of fat and meat cooking.
In the same manner, Christ on the cross dominates (or should dominate) the activities of the Christian Church. "And I, if I be lifted up, will draw all men unto me." The word altar has the root meaning of "slaying for sacrifice"; and the term burnt offering has the root meaning of "ascending toward God what is acceptable and pleasing to Him."
