He is the one! The only one! The only priest in all of history, in any religion, whose activities and sacrifice provided the help we all need. Jesus – The Great High Priest – is the source of eternal salvation.
Jesus and only Jesus offered the sacrifice that was sufficient to make atonement for our sins, and provide access for us to enter the presence of God. Our Great High Priest has provided a great salvation for us!
