It completely withstands scrutiny. The messianic world savior was taken from the Persians in 5BC and there are at least 6 dying/rising savior demigods who pre-date Christianity. This is all backed up by scholarship.
Also the bible is a bit unreliable because the gospels are not eyewitness and the others sourced from Mark. Mark uses a literary style that is used in metaphorical fiction and even copies OT narratives line by line to create new Jesus stories.
There are all kinds of excellent books by PhDs on these topics so to say it doesn't withstand scrutiny is incorrect.
There are verses in the Tanakh that talk about the second coming of Jesus. The prophecies about the second coming of Jesus arent mentioned there by Christians to make Jesus look credible-they were already there in the Jewish Bible.
Does the Old Testament truly predict a second advent of the Messiah? | GotQuestions.org
"Question: "Does the Old Testament truly predict a second advent of the Messiah?"
Answer: The Old Testament does prophesy the
second coming of Christ, also referred to as the second advent of the Messiah. Some Old Testament prophecies concern the first advent, when Christ was born as a human being. Others concern the second advent, which is the ultimate triumph of this Messiah. It’s important to remember that prophecy does not describe the future in the same detail as history describes the past. So, while the prophecies of the Old Testament certainly describe both the first and second advents, most early interpretations of these prophecies melded them into a single event. Particularly during the years leading up to Jesus’ birth, it was assumed Messiah would be a political/military figure with an immediate worldly kingdom (
Luke 19:11). In the light of Jesus’ ministry, it is possible to understand the true purpose of Christ and the real nature of His kingdom.
A careful look at Old Testament prophecies shows an underlying assumption of two advents.
Micah 5:2 and
Isaiah 7:14 predict the first advent. Separately,
Isaiah 53:8–9 predicts a
suffering and dying Messiah, who will be given life and greatness according to
Isaiah 53:11–12.
Daniel 9:26 describes the Messiah being killed after His appearance. At the same time, prophets such as Zechariah (
Zechariah 12:10) say this same “pierced” Messiah will be seen again by His enemies. So the clues are there.
Many Old Testament prophecies foretell the ultimate triumph of Christ, which will occur at the second advent. These include statements from the books of Zechariah (
Zechariah 9:14–15;
12:10–14;
13:1;
9:14–15); Amos (
Amos 9:11–15); Jeremiah (
Jeremiah 30:18;
32:44;
33:11,
26); and Joel (
Joel 3:1); which describe the Messiah coming in triumph to lead Israel into salvation. Note that these are in the context of passages such as
Deuteronomy 30:3–5and so are predictions of the time of Messiah’s final victory.
Also, Scripture records Jesus making direct comparisons to Old Testament prophecies when making His own claims to a second advent. For example, His words in
Matthew 24:31 and
Mark 13:27parallel the descriptions of
Isaiah 52:15 and
Isaiah 59—62.
All in all, the Hebrew Scriptures indicate that the Promised One would appear, be cut off, and then reappear in victory. The first advent has occurred; the second is still future. Both the New and Old Testaments predict a second advent of the Messiah."
