Revelation 2:10-11

10Fear nothing that you are about to suffer. Be aware that the devil is about to throw some of you into prison, that you may be tested [in your faith], and for ten days you will have tribulation. Be faithful to the point of death [if you must die for your faith], and I will give you the crown [consisting] of life.

11He who has an ear, let him hear and heed what the Spirit says to the churches. He who overcomes [the world through believing that Jesus is the Son of God] will not be hurt by the second death (the lake of fire).’
