And he shall lay his hand on the head of his offering and kill it at the entrance of the tent of meeting, and Aaron’s sons the priests shall throw the blood against the sides of the altar.
Leviticus 3:2 ESV
It’s a startling contrast. We read about the care in the tabernacle preparations. Skillful people took care in covering that altar with gold. The priests’ garments were clean and bedazzled with precious stones. Then the purity of the scene is interrupted with this violence. Blood is shed and tossed about like a crime scene.
There had been a crime. Violence had been committed. Enemies of God had their minds set on violence. Enemies of God had violated the law.
Many Christians have lost a proper view of sin. It’s an act of violence against God and His people. It’s a criminal act against a righteous judge.
Yes, we thank and praise God for mercy and forgiveness, but that comes after repentance and confession and falling on our faces before Him because of our offense.
