In order the show the superiority of trusting and following Jesus over the former covenant, the writer of Hebrews makes a comparison between the service of Jesus as our High Priest and the Levitical priesthood by saying:
“Also there were many priests, because they were prevented by death from continuing. But He, because He continues forever, has an unchangeable priesthood. Therefore He is also able to save to the uttermost those who come to God through Him, since He always lives to make intercession for them.” (Hebrews 7:23-25)
Many of us may think Jesus accomplished everything he sought to accomplish after he ascended to the right hand of the Father (Acts 2:229-36), but the writer of Hebrews enlightens our mind by showing us that Jesus still helps us even to this day as our High Priest before the Father in Heaven.
By the time the Hebrew letter had been written, thousands of Levitical priests had come and gone, but now, for nearly 2,000 years, Jesus has unchangeably stood as an intercessor for us, his people, and until the day the Father decides to send the Lord back, Jesus will continue to stand as the sole High Priest for our soul.
“For such a High Priest was fitting for us, who is holy, harmless, undefiled, separate from sinners, and has become higher than the heavens; who does not need daily, as those high priests, to offer up sacrifices, first for His own sins and then for the people’s, for this He did once for all when He offered up Himself. For the law appoints as high priests men who have weakness, but the word of the oath, which came after the law, appoints the Son who has been perfected forever.” (Hebrews 7:26-28)
