Is it not true that many of the prophecies that Jesus supposedly fulfilled were very well known about?

Question

And that he simply went around and did them, kind of like ticking off a list?

Answer 1

While it is true some of these prophecies are vague and could have been deliberately fulfilled, many are very specific that He had no control over. Examples:

Place of birth (Micah 5:2).

Date of birth (Daniel 9:25).

Manner of birth (Isaiah 7:14).

Manner of death (Zechariah 12:10; Psalm 22:16 prophesied before the invention of crucifixion).

Piercing in side (Zechariah 12:10).

Burial (Isaiah 53:9).

And so on ....

Answer 2

Even if they werent well known they were all right there in the Holy Books. He knew those well enough, be it from supernatural sources or from memorization earlier in life, no doubt he'd have known all the prophecy info no matter what.
