The very fact that God did not ensure non-tampering of the Bible shows that it doesn't belong to Him, nor any other scriptures because they all have been tampered with whereas Book of Nature cannot be tampered with by anyone. Many have discerned vital truths reading the Book of Nature.
Even if Bible somehow proved to be God's word, then problems are more because it has books in it contradicting to each other. If Damascus is destroyed we can say ok at the most some portion of the Bible is true.
But prophecy is not a too significant aspect because it can come from other source also:
For example, Craig Hamilton-Parker has had a streak
of correct predictions about significant developments in geopolitics.
Chiefly among them are Brexit, and the election of Donald Trump
As someone who sees the future, New Year's Eve is probably a
night without much wonder, or hopeful anticipation.
Hamilton-Parker has deigned to share his visions with us.
Speaking in a video posted to his YouTube channel, he predicted:
strikes in Britain.
- A US
warship will sink.
Jong-un will be overthrown.
Harry and Meghan Markle will announce an engagement.
Trump will survive an impeachment attempt.
volcano near Naples will erupt (possibly Mt. Vesuvius)
large chunk of Antarctica will break away.
Writing on his blog, Hamilton-Parker said that despite this
gloomy list, the year 2018 will have some good moments.
2018 will be a year of political turmoil
and environmental crisis caused by dramatic and unprecedented weather.
