There were a lot of hoops Aaron and his sons had to jump through before they could do the work of the priests. From the top of their heads to the tip of their toes, from what they ate to where they ate it, from what animal they used in the sacrificed to what they did with every inch of the animal, nothing was left to chance. Their instructions, which were many, were clearly spelled out so the Jews could have their sins forgiven.
But after all that, even if carried out to the letter, the ceremony and sacrifices could only cover their sins, none of it could actually take those sins away. (Heb 10:4)
Only Jesus can do that. (Heb 9:15, 26; Romans 3:23)
Scripture tells us that when Jesus offered Himself as the perfect sacrifice, He washed our sins away, removed them as far as the east is from the west, buried them in the deepest sea, and promises never to remember them ever again.
What we read in Exodus is a picture of the intricate details Jesus fulfilled. But He went a step further. And I am praising Him today because He did!
