Christian scripture is no more meaningful or authoritative to me than Islamic scripture is for either of us.. You needn't cite it as evidence of anything more than that somebody wrote it and it wound up in the Bible.
The Bible did not foretell what would be happening now. Biblical prophecy is mostly vague and nonspecific. It has never prepared us for any event. Telling us that there would be wars and earthquakes isn't any more prophetic than telling us that it will be dark tonight and that somewhere, someone will be born and someone will die before the sun reappears..
Please note the magnitude of earthquakes that would be occurring now > It says ' great ' earthquakes <- Luke 21:11
Earthquakes coupled with a composite sign of many other things happening at the same time couple with the international global proclaiming about the good news of God's kingdom on a world-wide scale as being done today.
How do one know Bible prophecy is vague if one has never studied the Bible.
What is vague about the people's behavior according to 2 Timothy 3:1-5,13
What is non-specific about 1 Thessalonians 5:2-3 when ' they ' (powers that be) will be saying, " Peace and Security " as a precursor to the coming great tribulation of Revelation 7:14.
