Vs. 1, “Aaron’s sons Nadab and Abihu took their censers, put fire in them and added incense; and they offered unauthorized fire before the Lord, contrary to his command.” Nadab and Abihu sinned against the LORD. Our God is a consuming fire. It is quite a contrast from the celebration just earlier with the glory of the LORD in the tabernacle. I’m reminded of that statement, “with great privilege brings great responsibility.” While they used an unauthorized fire source, there was more to it than this. It was not their responsibility, but their father Aaron’s. Much like Ananias and Sapphira (Acts 5), this was a new beginning with God’s people. There needed to be a standard set that let the people know God was not one to be manipulated or disobeyed.
Regarding application…God Knows Our Hearts. Vs. 19, “Aaron replied to Moses, “Today they sacrificed their sin offering and their burnt offering before the Lord, but such things as this have happened to me. Would the Lord have been pleased if I had eaten the sin offering today?” Though Aaron and his two other sons were not allowed to mourn outwardly the death of their family members (Nadab & Abihu), we see here the grace of God. They were supposed to have eaten the sin offering that was sacrificed (vs. 16-18). It was their way of grieving the loss. Grace was given to them that day. The point was made clearly and now it was time for the LORD through Moses to show grace. He knew their hearts. Take comfort in knowing that God sees both our actions and our hearts.
