Leviticus 16:12

Leviticus 16:12 And he shall take a censer full of coals of fire from the altar before Jehovah, with his hands full of finely ground fragrant incense, and bring it inside the veil.

The burning of the incense after the slaughtering of the sin offering, so that Aaron would not die, signifies that in His resurrection the Lord Jesus became a sweet fragrance to be the means and the protection for us to draw near to God with all boldness and be accepted by God without suffering death. This is one of the results produced through the redemptive, blood-shedding death of the Lord Jesus on the cross.

The incense was burned with the fire from the altar in the outer court, signifiying that Christ's being burned as the incense for our acceptance before God depends on His death on the cross for our sins. Christ first became the offerings to take away our sin; then, in His resurrection, with His death on the cross as the basis, He became the incense for our acceptance.
