Revelation 2:2

2:2 ‘I know your works as well as your labor and steadfast endurance, and that you cannot tolerate evil. You have even put to the test those who refer to themselves as apostles (but are not), and have discovered that they are false.

Revelation 13:10

13:10 If anyone is meant for captivity,

into captivity he will go.

If anyone is to be killed by the sword,

then by the sword he must be killed.

This requires steadfast endurance and faith from the saints.
