Christianity Today has a review of End of the Spear. We haven't yet seen the movie, but it's based on a truly amazing story. For those not familiar with it, in 1956 four young missionaries were murdered by Ecuadoran indians. After their deaths, two of the widows and a sister of another of the slain men went to live with the tribe from which the killers came. Because of the beauty of their witness, eventually much of the tribe, including the killers, was converted to Christianity.
It is very difficult to imagine the selflessness of bereaved women who might have been understandably embittered toward the murderers of their loved ones, instead going to live among the killers to win them to the Truth. It is an amazing story of love, forgiveness, redemption, and human nobility, and from all that we've heard and read the movie tells it faithfully and powerfully.
