The word martyr is only used twice in the whole Bible. However, if you look up what it means in the Greek, it's literal meaning is "a witness". This is very interesting to me. Stephen, the first martyr of the Church, witnessed not only with his words, but also his death (Acts 7).
T.S. Eliot described a martyr as one "who has become an instrument of God, who has lost his will in the will of God, not lost it but found it, for he has found freedom in submission to God. The martyr no longer desires anything for himself, not even the glory of martyrdom."
What do you think a martyr is?
