The Bible instructs us that our leaders and teachers in the church must live Godly lives to set an example. Although the topic is dear to Christians, this is not a Sunday School lesson. End of the Spear is a motion picture with a wonderful message, marketed as entertainment to the world at large. The great message is in no way compromised by the actors, whatever their sins may be.
Some non-Christians will be moved by this story and will explore further. In looking further, they may discover life-changing Truth. Unfortunately, they won't have much more time, because this film won't be in theaters too much longer, in great part because of hysteria caused by misguided Christians. Maybe they'll go see Brokeback Mountain instead.
Okay. My thoughts were only to share what I have come to understand from much study about what scripture has to say about homosexuality. I have three friends from years gone by that are homosexual. I study to show myself as one approved as Timothy admonishes us to do. My concern is that compromise can be so subtle and cause us to stumble.
I hope the movie does help someone find Christ--maybe even the actor in question? I am only sharing what I think, I look not to divide.
