Yeah, I understand what you're saying. But for those young men and women who see the movie, and are attuned to God's grace, they may be moved and deepened in their faith. In short, those who don't understand what they're seeing won't benefit. Others may come closer to God as a result.
. . . as many who have watched the Jesus video have. Granted, Campus Crusade for Christ's Jesus video is not a splashy Hollywood production, but an accurate, well-made Gibson film could be an instrument in the Lord's hands.
