Historical context

What was happening when this word was written?

Roman Empire under Domitian (c. AD 95)

Domitian required people across the empire to address him as Dominus et Deus — Lord and God. Christians who refused to burn incense before the emperor's image faced economic exclusion and imprisonment. The book was written in apocalyptic imagery that believers would recognize but Roman authorities would not — a letter of resistance written to people being crushed by the most powerful empire on earth.

The people who first heard this word were not reading a book — they were living through empires, oppression, exile, and covenant. Every word carried the weight of that reality. Understanding it changes how you read Scripture.
