Leviticus 10: Fire from the Lord--Again

The glorious scene that ends the previous chapter involves fire from the Lord. One of the key factors has to do with the offerings. Those of chapter nine followed the instructions. That of chapter ten included something that was “strange” [not authorized]. They had no right to offer this fire because God had not given His approval in any way. So they died. Are the offerings that I present to Jehovah authorized? Or are they “strange” to Him? See Hebrews 12:29.
