“Lets not blame God for incurable bugs. He has a time set aside to punish those that deserve it, but presently his judgements are reserved for ‘Nations,’ according to his word.”
Biblically “incurable bugs” can certainly be a judgment from God, whether nationally or individually.
Deuteronomy 28:27
The Lord will strike you with the boils of Egypt, with tumors, with the scab, and with the itch, from which you cannot be healed.
But WHERE does God’s word say that currently God’s judgment is only upon Nations?
Biblically, national judgements only.
(as the example you posted illustrates)
Individuals will be judged “according to their deeds,” when the books are opened.

Revelation ch 20 reveals his judgement plan.
