"The former priests were many in number, because they were prevented by death from continuing in office, but [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."
(Heb 7.23-25 ESV)
Imagine someone who holds a non-stop prayer meeting for us 24/7, an unrelenting supplication for nothing but salvation for us. This is our reality in the Lord Jesus Christ!
Adam Clarke, in his Commentary, notes on verse 25:
"Wherefore - Because he is an everlasting priest, and has offered the only available sacrifice, he is able to save, from the power, guilt, nature, and punishment of sin, to the uttermost, εις το παντελες, to all intents, degrees, and purposes; and always, and in and through all times, places, and circumstances; for all this is implied in the original word: but in and through all times seems to be the particular meaning here, because of what follows, he ever liveth to make intercession for them; this depends on the perpetuity of his priesthood, and the continuance of his mediatorial office. As Jesus was the Lamb of God slain from the foundation of the world, has an everlasting priesthood, and is a continual intercessor; it is in virtue of this that all who were saved from the foundation of the world were saved through him, and all that shall be saved to the end of the world will be saved through him. He ever was and ever will be the High Priest, Sacrifice, Intercessor, and Mediator of the human race. All successive generations of men are equally interested in him, and may claim the same privileges. But none can be saved by his grace that do not come unto God through him; i.e. imploring mercy through him as their sacrifice and atonement; confidently trusting that God can be just, and yet the justifier of them who thus come to him, believing on Christ Jesus."
You have a High Priest; therefore, you have a prayer.
