Affirming Mark 1:15
==============================================
Dan 9 has a 70 weeks (490 days... becomes day-for-year 490 years) timeline predicting the coming of Christ.
Then in
Mark 1:15 Christ says that the prediction of the first part -
the 483 years is fulfilled with the start of His ministry
Mark 1:
9 In those days Jesus came from Nazareth in Galilee and was baptized by John in the Jordan. 10 And immediately coming up out of the water, He saw the heavens opening, and the Spirit, like a dove, descending upon Him; 11 and a voice came from the heavens: “You are My beloved Son; in You I am well pleased.”
12 And immediately the Spirit *brought Him out into the wilderness. 13 And He was in the wilderness for forty days, being tempted by Satan; and He was with the wild animals, and the angels were serving Him.
14 Now after John was taken into custody, Jesus came into Galilee, preaching the gospel of God, 15 and saying, “The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel.”
16 As He was going along the Sea of Galilee, He saw Simon and Andrew, the brother of Simon, casting a net in the sea; for they were fishermen. 17 And Jesus said to them, “Follow Me, and I will have you become fishers of people.” 18 Immediately they left their nets and followed Him.
In Mark 1 we see
the start of Jesus' ministry and it includes the message
that the Dan 9 timeline predicting the exact year of Christ's first coming - had been fulfilled.
Dan 9:
24 “Seventy weeks have been decreed for your people and your holy city, to finish the wrongdoing, to make an end of sin, to make atonement for guilt, to bring in everlasting righteousness, to seal up vision and prophecy, and to anoint the Most Holy Place. 25 So you are to know and understand
that from the issuing of a decree to restore and rebuild Jerusalem,
until Messiah the Prince, there will be seven weeks and sixty-two weeks; it will be built again,
with streets and moat, even in times of distress. 26 Then after the sixty-two weeks, the Messiah will be cut off and have nothing
We find information about that decree referenced above in Dan 9 --- in Ezra 6,7 and in Ezra 9k
Ezra 6 tells us it is a 3-part decree with Cyrus, Darius and Artaxerxes all contributing to it.
14 And the elders of the Jews were successful in building through the prophecy of Haggai the prophet and Zechariah the son of Iddo. And they finished building following the command of the God of Israel and
the decree of Cyrus, Darius, and Artaxerxes king of Persia.
Ezra 7: 8-9 --- in 457 B.C.
8 And he ( Ezra the priest) came to Jerusalem in the fifth month, which was in the seventh year of the king.(Artaxerxes king of Persia) 9 For on the first day of the first month he began to go up from Babylon; and on the first of the fifth month he came to Jerusalem, because the good hand of his God was upon him. 10 For Ezra had firmly resolved to study the Law of the Lord and to practice it, and to teach His statutes and ordinances in Israel.
11 Now this is the copy of the letter which King Artaxerxes gave to Ezra the priest, the scribe, learned in the words of the commandments of the Lord and His statutes to Israel: 12 “Artaxerxes, king of kings, to Ezra the priest,
(vs 15-23 treasures, gifts, gold to be sent with Ezra)
Ezra's prayer
Ezra 9:9 For we are slaves; yet in our bondage our God has not abandoned us, but has extended favor to us in the sight of the kings of Persia, to give us reviving to erect the house of our God, to restore its ruins, and to give us a wall in Judah and Jerusalem
======================
Dan 9 is given as an "explanation" to the vision of Dan 8... because among other things - Dan 8 has no start date and Dan 9 gives an exact start date.
Dan 9 is the only OT prophecy with a timeline pointing to the start date of the Messiah's ministry.
So then the 490 years of Dan 9 starts in 457 B.C.
And the 2300 years (day for year) in Dan 8 start in 457 B.C.
Step 1 - look at the actual texts as noted above
Step 2 - math
Until you notice how many of them affirm Mark 1:15 and the fact that Jesus' ministry began early in the first century - and the fact that the OT predicted the first coming of Christ...
How about a discussion of "the details" then - because Dan 7 ALONE already established the fact of a pre-advent investigative (out of books) judgment where "judgment is passed in favor of the saints" Dan 7:22 and the Judgment event is explicitly stated in vs 9-11.
Until you read Daniel 7.
