Hebrews 7:11-17, There was a need for a better Priest, an eternal one
Upgrades has become a normal part of our everyday lives in the technology driven society in which we live. Items swiftly become outdated and replaced with new items with better features. Apple comes out with new iPhone yearly as technology changes and grows, when you buy a laptop it is probably out of date before you get it home, and new models of vehicle are constantly rolling off the assembly line that surpasses the last model. The reason there is constant upgrades is because their room for improvement or advancements, perhaps one day someone will create a device that can not be improved upon. This is exactly what happened with the priesthood of mankind, there was need for improvement but when Jesus filled the position there is no way it could ever be improved upon. Verse 16 says that men became priests through ancestry under the Jewish law, but Jesus assumed the role based on indestructible life.
There have been some great individuals serve in the role of ministers on the earth over history, but they all have one thing in common, they all have flaws. They have all fallen short of the glory of God, they all have sin in their lives. They can’t intercede on your behalf with God unless they first interceded on their own behalf first. Jesus broke the mold; Jesus can intercede on our behalf before God with no shame and no blemish because He is without sin. 2 Corinthians 5:21 says that He who knew no sin, became sin for us, that we might become the righteousness of God in Him. He isn’t a priest that needs to make a sacrifice for His sins, He is the priest who made Himself a sacrifice for the sins of all mankind. There was a need for a better priesthood, but that is no longer the case, Jesus is the priest who walks and dwells in perfection.
