There was a time when God was not nearly as full of grace as He appears today. In the time of Moses, He gave specific instructions on how He required His temple to be built and its' ordinances to be observed. Some thought they had a better idea and died for their creative genius or stupidity. It just depended on which side of the flame you stood as to your attitude.
"That same day Nadab and Abihu, Aaron's sons, took their censers, put hot coals and incense in them, and offered "strange" fire to God—something Godhad not commanded. Fire blazed out from Godand consumed them—they died in God's presence." ~Moses
The priest had a tremendous responsibility to get things right before God. There was a price to pay for "errors". Today, as believers in "The Way", we are individually held as priests. We seem to goof up a lot of the time. It is truly by the grace of God, we are allowed each a new day to try and do better at what God has entrusted.
I pray today will be the day, we each bring a satisfying fragrance before God and He is honored by our thoughts and deeds.
