The qualification for martyrdom is simply one of position...that is being "born again in Christ"....then the outworking of being a martyr
would come from those who oppose scriptural truth, usually because these persecutors hate their darkness
being exposed. You only need to get vocal about your faith at work, in the street, or any public place for that matter to experience persecution. Taken to the extreme this persecution ends in death. While it is true that every religion can and does claim varying degrees of persecution, non are more persecuted than believers in Christ. Right now every day around 500 Christians "per day" die for their faith at the hands of those who hate Christ and all He stands for? Somber thoughts I know, but it is the truth.
