The two priests had only tried to offer incense to the LORD. It would seem like something perfectly normal for consecrated priests to do. But the LORD had not commanded the offering, and Aaron’s two sons, ceremonially unclean before the LORD, paid with their lives.
The book of Leviticus, with its detailed explanations of God’s law, can be challenging for modern readers. And if the practical task of setting down ceremonial regulation was the only purpose of the book, it would indeed be tiresome to read. But that isn’t God’s only purpose with this section of Scripture. Certainly, he wants to show what he expects his people to do, but his law also demonstrates who he is - and, in turn, who his people are: chosen, set apart for God’s purpose.
Later, In the Gospel of Luke, God’s people turn the question of identity against Jesus. They look for miracles and justice, on their own terms, as evidence of his divinity. They have become so intent upon following the law that they do not recognize its fulfillment in Jesus.
We, the new Israel, do this, too. Rather than recognizing our sin before the LORD, we demand instead that he prove himself. We want healing for ourselves and thunderbolts for our enemies, while the true enemy, death, has already been overcome in Jesus’ resurrection, and the true healing of our sinsickness is there for the taking - if only we would hear and see it in his Word.
Mercifully, our baptism into the death and resurrection of Jesus has made us clean. The anger of the LORD will not consume us. Jesus himself dwells in our midst with his pronouncement of forgiveness to penitent hearts, and he continues to offer it fully and freely. Following him may cost us much in worldly terms, but the treasures of life and salvation surpass all of it.
For God’s people in every age, the echo of Easter rings.
