Christianity also teaches about a priest and a sacrifice; but unlike the Old Testament, both the priest and the sacrifice are the same one -- Jesus. Scripture tells us that Jesus "has appeared to put away sin by the sacrifice of Himself." (Hebrews 9:26) In John chapter 10, Jesus said, "I am the good shepherd...I lay down My life for the sheep...I have power to lay it down, and I have power to take it again. This command I have received from My Father."
Praise be to the Priest and Lamb!
