Le 9:24 and fire came out from before the LORD and consumed the burnt offering and the fat on the altar. When all the people saw it, they shouted and fell on their faces.
After the animal sacrifice (the burnt offering) was offered on the altar, fire came out from God and consumed it. The fire from God was a symbolic demonstration of His acceptance of the sacrifice. Instead of His judgment falling on them, it fell on the symbolic sacrifice.
All these were symbols pointing to the real efficacious sacrifice on the cross of Calvary. The sacrifice was a symbol of the Lord Jesus Christ on the altar of the cross of Calvary. There, the wrath of God fell on Him. There, on the cross, He was consumed by the wrath of God. God owned Him as Man's sacrifice for his sins.
The question is --- Do we accept Him, trust in Him and what He did on the cross, as the satisfactory sacrifice that could appease the wrath of God against us?
