It would be very sad for any person to not know what Jesus does in His "office" on our behalf,
"where He ever liveth to make intercession for us" (Hebrews 7:25)
"And if Christ be not raised, your faith is vain; ye are yet in your sins." (1 Corinthians 15:17).
We are not able to enter into heaven alone, because we are unworthy, but can only enter in through Jesus who has paid the price of our sins.
For this reason we are dependent on Jesus being in heaven in the first place.
Jesus' role as high priest is truly everlasting, because unlike the high priests of Aaron He will never die (Hebrews 7:23).
"But this man, because he continueth ever, hath an
UNCHANGEABLE priesthood." (Hebrews 7:24)
It makes absolutely no sense to claim that Jesus is going to re institute a Levitical priesthood, because He is from the tribe of Judah, and His priesthood is of a superior order than that of Levites.
Because Jesus has risen and entered his "office" the priesthood has been changed, and "For the priesthood being changed, there is made of necessity a change also of the law" (Hebrews 7:12).
"For there is verily a
DISANNULLING of the commandment going before for the weakness and unprofitableness thereof" (Hebrews 7:18).
The word "disannul" means to make void.
That is what has happened to both the law of Moses, and to the Levitical priesthood, together with the role of the earthly temple and the animal sacrifices.
That is also why Jesus will not come back as an earthly king and do all of those things.
He is ready to judge the world once and for all as soon as the last person that He intends to save is saved.
He will not abandon His role in Heaven, but rather bring his people there to join Him-
"Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them." Hebrews 7:25.
Romans 8:34
Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also
maketh intercession
for us.
So that ai study on the use of "forever" did not get everything right.
It did however correctly list some conditional promises that were "forever" from the intention of God, but broken by man and therefore disannulled.
Interesting that it omitted to tell us that the land promise falls in that category.
