Then Nadab and Abihu, the sons of Aaron, each took his censer and put fire in it, put incense on it, and offered profane fire before the Lord, which He had not commanded them. So fire went out from the Lord and devoured them, and they died before the Lord. Leviticus 10:1-2
This is serious. God is serious.
Then the glory of the Lord appeared to all the people, 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. (Leviticus 9:23-24)
But these two sons of Aaron got up and rushed into the presence of God, paying for it with their lives.
It may seem harsh. Why not a reprimand? Why not some leniency?
These two did not do this out of ignorance.
They knew their duties and requirements but stepped beyond those boundaries.
God is holy and just. He is due all respect.
It is sad to fall in the judgment of God with no advocate or mediator.
God’s demands of holiness are not changed. You find holiness in obedience to His word. That was true in the time of Moses and true today.
Although salvation was veiled in mystery during the time of Moses, His word says the sacrifice of Jesus is the chosen way of salvation.
Anyone that attempts to rush around Him with their own sacrifice will suffer in His judgment.
And I saw the dead, small and great, standing before God, and books were opened. And another book was opened, which is the Book of Life. And the dead were judged according to their works, by the things which were written in the books. Revelation 20:12
And anyone not found written in the Book of Life was cast into the lake of fire. Revelation 20:15
