Martyr's Mirror presents a history of Christian martyrs who set their minds on things above and overcame the evil one. Some of greatest treasures in the book, Martyr's Mirror, are the letters of the martyrs written to their families and friends. They wrote about their emotional and spiritual struggles as their executions approached. They wrote of the comfort and great joy received from God. They sent letters of encouragement to those left behind, urging them to stand strong in the faith. One martyr wrote, "I feel that it is all of the Lord, for when I for a time hear of no deliverance, I receive great joy in my heart and refreshing from the Lord; but as soon as something comes again, and the flesh lusts greatly after it, joy departs, and we have great difficulty to get it back from the Lord. These martyrs joined the "great cloud of witnesses" who left their testimonies for us. The complete Martyrs Mirror is still available for purchase. It is 1,150 pages, which scares most readers. I highly recommend it. But if you aren't inclined to read the whole book, then Martyrs Mirror Treasures will give you many rewarding passages in the larger book.
