It (op trust) is within the realm given what we know and can identify as fact.

That said, I tend to think Biblical might refer to the fact that we have no choice in fighting off those who would want to bring on the antichrist and try to speed things up with all their might. It is an ideological war we are fighting (not by choice) and one that will not be dissuaded by ‘talk’. Those waging it believe they are doing God’s work and will stop at nothing - it will be Biblical.

It certainly could be more literal than this, on a few, or many levels. Kind of depends on what you believe (in).
