As an example of a parable notice the following comparison –
Da 9:26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
The person mentioned in verse 26 is Messiah.
Then verse 27 begins with a reference to Messiah by using the word “He”. The word “He” in verse 27 refers to Messiah. Messiah refers to Jesus.
Daniel 9:27 says that Jesus will confirm the covenant with many for one week or time.
During or in the midst of that week Jesus will cause the sacrifice to cease.
At this point, where the sacrifice ceases, we find the situation describes the phrase found in Heb 10:26.
Therefore the situation where Jesus causes the sacrifice to cease is the point at which a person chooses to willfully sin.
When a man chooses to willfully sin they become a man of sin (2 Thess 2:3) and God sends them a delusion so that they believe a lie and won’t repent so that they can be judged, 2 Thess 2:11).
2Th 2:11 And for this cause God shall send them strong delusion, that they should believe a lie:
(KJV)
2Th 2:12 (ASV) that they all might be judged who believed not the truth, but had pleasure in unrighteousness.
Heb 10:26 For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
27 But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
This will result in a certain judgment which will devour or consume the adversaries or more appropriately the fiery judgment devours “that which opposes”.
Keep in mind that Daniel 10:27 says that these events happen while Jesus is confirming the “covenant with many”.
These events are now seen to be referring to Jesus delivering a person over to fiery judgment as a part of the covenant that the person made with Him.
This is in keeping with De 28:2 and De 28:15. The principles in these verses apply today. Only the method of obtaining forgiveness has changed.
De 28:2 And all these blessings shall come on thee, and overtake thee, if thou shalt hearken unto the voice of the LORD thy God.
De 28:15 ¶ But it shall come to pass, if thou wilt not hearken unto the voice of the LORD thy God, to observe to do all his commandments and his statutes which I command thee this day; that all these curses shall come upon thee, and overtake thee:
When willful sin happens Jesus delivers the person who has made a covenant with Him over to fiery judgment that will devour that which opposes or stands in opposition to the covenant.
Per 1 Cor 11:32, this is seen to be the sinful tendencies and not the person themselves.
1Co 11:32 But when we are judged, we are chastened of the Lord, that we should not be condemned with the world.
In conclusion, what Daniel 9:26 and 27 are referring to is the correction that is a part of the covenant.
This correction is controlled by Jesus and is designed to conform the person into His image. Only patient endurance is required on the part of the one being chastened.
