The Lord said through his prophets that HE would forgive them their iniquities and would remember their sins no more. It is the people who glory in sin. But what saith the scriptures, shall not GRACE abound the more? But from the standpoint of God, he declared an end of sin so that He could make reconciliation with his people. As it is written, God is a God of the living and not the dead (Matt 22:32); For to this end Christ both died, and rose, and revived, that he might be Lord both of the dead and living (Rom 14:9).
Galatians 4 talks about the two Jerusalem's, which are an allegory for the two covenants. The new Covenant is of the Spirit. But I find it interesting that Paul states that the desolate (old covenant, those without a husband) have many more children than She (new Jerusalem) which has a Husband. Now that's something to think about. Just who are the people who have prophesied in is name and cast out demons in his name, and have done many great works in his name, but Jesus says he never knew you, depart from me you workers of iniquity.
I think as it pertains to this discussion about Daniel 9:24-27, the people of the prince who shall come, the Bride of Christ and the destruction of Jerusalem, it would probably be a good time to meditate on the parable of the marriage feast, and let the Spirit of Christ speak to your heart.
Matthew 22:1-14
And Jesus answered and spake unto them again by parables, and said, The kingdom of heaven is like unto a certain king, which made a marriage for his son, And sent forth his servants to call them that were bidden to the wedding: and they would not come. Again, he sent forth other servants, saying, Tell them which are bidden, Behold, I have prepared my dinner: my oxen and my fatlings are killed, and all things are ready: come unto the marriage. But they made light of it, and went their ways, one to his farm, another to his merchandise: And the remnant took his servants, and entreated them spitefully, and slew them. But when the king heard thereof, he was wroth: and he sent forth his armies, and destroyed those murderers, and burned up their city. Then saith he to his servants, The wedding is ready, but they which were bidden were not worthy. Go ye therefore into the highways, and as many as ye shall find, bid to the marriage. So those servants went out into the highways, and gathered together all as many as they found, both bad and good: and the wedding was furnished with guests.
And when the king came in to see the guests, he saw there a man which had not on a wedding garment: And he saith unto him, Friend, how camest thou in hither not having a wedding garment? And he was speechless. Then said the king to the servants, Bind him hand and foot, and take him away, and cast him into outer darkness; there shall be weeping and gnashing of teeth. For many are called, but few are chosen.
He has called you to the marriage feast, he has given you the Spirit of Christ for a wedding Garment, but still you will not come.
A final parting thought. Do the people who believe that the 70 weeks are actually 490 years, and that somehow there is a 2000 year gap between the 69th and 70th week also insist that the creation account in the Book of Genesis is literally 7 consecutive 24 hour days?
