Neil said something in a post recently, which has sparked these thoughts.
In at least one of his sermons (or Q&A sessions), Paul Washer describes a scenario when a group of workers might have been approached by a group of soldiers to be asked to swear that Caesar is god. If they don't they will be summarily slaughtered. Christians regularly failed this examination.
The other verse I thought of [Luke 21:15 For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist.] seems intense in its own way, but appears to imply that like Jesus often spoke to the Pharisees, and they didn't ask Him any more on that occasion, we too will be given wisdom beyond natural understanding, but not be facing imminent death. (However, perhaps we are being prepared for it further down the line.)
My question comes from Revelation 12:11
And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
(I found the 'Testimony of the Blood', with extracts from Sparks, here: https://www.sermonindex.net/modules/newbb/viewtopic.php?viewmode=thread&order=0&topic_id=3270&forum=34&post_id=)
What is actually in 'the WORD of [our] testimony'?
Is it simply that 'Jesus Christ is Lord!' or, does it vary with the situation?
