Powerful faith affects all with whom it comes in contact. Some will be inspired to imitate what they see; but most only become angry when they see such faith. They cannot live with the truth about their own spiritual poverty, and so they attack those who have shamed them. They call them "heretics", "fanatics", "cults". And they seek to have them silenced, if not destroyed.
The Revelation talks of a great multitude which could not be numbered (in addition to the 144,000 saints who are sealed by God before the Great Tribulation begins). It says that these people will wear white robes when they stand before God, robes which have been washed clean in the "blood of the Lamb". (Revelation 7:9, 14-17)
The "blood of the Lamb" symbolises the blood that Jesus spilled for all of us when he was crucified. But Jesus also asked us to take up our own crosses and to follow in his footsteps. The Revelation says that during the Great Tribulation, believers will be able to spiritually triumph over the Antichrist "by the blood of the Lamb, and by the word of their testimony, and by the fact that they loved not their lives, even in the face of death." (Revelation 12:11)
All indications are that the great multitude that "comes out of great tribulation" will actually be martyrs, following the Lamb to their deaths. The Revelation specifically says of them that they will be "beheaded". (Revelation 20:4)
