Hebrews 7:23-25 ESV

“The former priests were many in number, because they were prevented by death from continuing in office,  but he (Jesus) holds his priesthood permanently, because he continues forever.  Consequently, he is able to save to the uttermost those who draw near to God through him, since he always lives to make intercession for them.”

Jesus, our high priest, was the sacrifice for all of our sins forever. He never leaves His post, never stops interceding on our behalf, always stands in the gap for us, always gives us wise counsel. He is the greatest High Priest forever!
