Well, maybe there are Christians in the west who have died for their faith already, it might just be that it has not been made known.
As far as persecution goes, we should have learnt by now from Christians in communist and islamic nations, who have been persecuted and put to death for their faith for decades.
Had they hid their faith, they would not have been persecuted or might still be alive today.
Here is a scripture that I do not like, but, it says what it says, Rev 13v7, 'It was granted to him to make war with the saints and to overcome them. And authority was given him over every tribe, tounge, and nation.'
Scripture tells us that he overcomes the saints, that's what I don't like about it.
It doesn't mean the power of God has no effect, it means prophecy is being fulfilled, as it did when the Lord Jesus Christ was crucified.
Obedience unto death? The apostle Paul tells us in 2 Cor 11v1 to imitate him as he imitates Christ.
Consider Christ's obedience concerning the cross.
We should be obedient unto death. That is what the Christian walk consists of.
11 of the 12 apostles were martyred.
Much to think about. Much.
