Hebrews 9 begins with the author showing us a picture of the tabernacle that existed in the Old Covenant as a place for Israel to atone for their sin. There were some issues with this tabernacle though. First is that the rituals had to be done over and over, they were never complete. And secondly, all of the offerings were not enough to perfect the conscience of man. Only Jesus and HIS work could do that. This is a great study in who and how our conscience is perfected!
