Hebrews 9:23-28

Again in this passage Christ is a more perfect sacrifice and a more perfect priest. All the animal sacrifice before was just a copy of heavenly things. Christ entered heaven and did it once to finish with sin. Christ takes away the sins of many this way and offers it to us. Again what Christ did was complex. It wasn't a simple thing that anyone else could have done. It was all done to fulfill law and balance justice. God is good to us to offer us such a thing. We shouldn't look at it so lightly but really be thankful for it. There's a lot to be thankful for when you receive eternal life for free.
