The priests represents many things in the Hebrew scriptures. They are mediators. They processed what was brought to them in a special way.
"The Levitical priests, all the tribe of Levi, shall have no portion or inheritance with Israel. They shall eat the LORD's food offerings as their inheritance." - Deuteronomy 18:1 ESV
"And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen." - Revelation 1:6 KJV
We are a kingdom of priests... a royal priesthood. Our inheritance is different.
"Speak to Aaron and his sons, saying, This is the law of the sin offering... The priest who offers it for sin shall eat it. In a holy place it shall be eaten, in the court of the tent of meeting... And the earthenware vessel in which it is boiled shall be broken. But if it is boiled in a bronze vessel, that shall be scoured and rinsed in water. Every male among the priests may eat of it; it is most holy. But no sin offering shall be eaten from which any blood is brought into the tent of meeting to make atonement in the Holy Place; it shall be burned up with fire." - Leviticus 6:25a, 26, 28-30 ESV
Notice how the clay vessels used to 'process' the offering are broken but the bronze ones are scoured and washed.
Earthen vessels speak of humanity.
"But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us." - 2 Corinthians 4:7 KJV
We are shaped things. Beautiful fragile and porous.
God's things are durable.
"But all silver and gold, and every vessel of bronze and iron, are holy to the LORD; they shall go into the treasury of the LORD... And they burned the city with fire, and everything in it. Only the silver and gold, and the vessels of bronze and of iron, they put into the treasury of the house of the LORD." - Joshua 6:19, 24 ESV
Jesus' earthen vessel was broken when he made an offering for our sin but God washed off the bronze vessel of His divine judgement.
The doctrine of the cross is a divine concept. It is unchanged by circumstances and time. It can be reused again and again but we are earthen vessels porous and fragile. If we process sin through our self life we will set ourselves up for destruction.
We need to let sin be processed by the doctrine of the cross. It is bronze and durable. The doctrine can be rinsed off and reused. The stress of processing sin is to much for us. We must live in newness.
Let's bring everything that has to do with sin and process it in the holy place. The offering goes in but nothing comes out again. The only thing that should leave the temple is ashes and even those are brought into the wilderness and left there where no one can find them.
