“And the LORD called unto Moses, and spake unto him out of the tabernacle of the congregation, saying, ‘Speak unto the children of Israel, and say unto them, If any man of you bring an offering unto the LORD, ye shall bring your offering of the cattle, even of the herd, and of the flock. If his offering be a burnt sacrifice of the herd, let him offer a male without blemish: he shall offer it of his own voluntary will at the door of the tabernacle of the congregation before the LORD. And he shall put his hand upon the head of the burnt offering; and it shall be accepted for him to make atonement for him. And he shall kill the bullock before the LORD: and the priests, Aaron’s sons, shall bring the blood, and sprinkle the blood round about upon the altar that is by the door of the tabernacle of the congregation. And he shall flay the burnt offering, and cut it into his pieces. And the sons of Aaron the priest shall put fire upon the altar, and lay the wood in order upon the fire: and the priests, Aaron’s sons, shall lay the parts, the head, and the fat, in order upon the wood that is on the fire which is upon the altar: but his inwards and his legs shall he wash in water: and the priest shall burn all on the altar, to be a burnt sacrifice, an offering made by fire, of a sweet savour unto the LORD.” Leviticus 1:1-9 (KJB)
The book of Leviticus is about holiness, God’s requirements for the holiness of His people, Israel and for Christians. The command to be holy is carried on to and through the New Testament (1 Peter 1:16).
As Christians we know that we have no holiness of our own; we are rather dependent upon the holiness of Christ, and His Spirit to fill us daily so that we might wholly and in holiness live for Him and glorify His name.
The theme of the fire of God is carried into the present day as well to burn away the lust of the flesh and the power of the devil (Hebrews 10:31; 12:28-29). The fire devouring our sin is a sweet smelling savor unto the LORD.
The fiery wrath of God was poured out onto His Son when He became sin for us (2 Corinthians 5:21), devouring our sin; and He leaving them in the heart of the earth [the grave] crushed the head of Satan, and rose the Victor from that dark domain; and He forever lives and daily intercedes for us. We need no other priest or intercessor, but Christ Jesus.
