I was asked not long ago how I became a Christian. God used a series of things/events/people who brought it about. One of the more bizarre events occurred during my senior year in high school - I saw the movie "The Seventh Sign", starring Demi Moore. It was an apocalyptic film about the Seven Seals foretold in the Book of Revelation to bring about the end of the world. For some reason the movie caught my attention and prompted me to begin to read the Bible for the first time... it began a journey for me that has really never ended.
Years later, after seminary, I re-watched "The Seventh Sign" and was surprised how inaccurate the movie was according to the Scriptures. Though some of it was biblical, much of it was taken from legends and ancient mysticism. Theologians and the Christian community roundly criticized it; and yet there is little doubt in my mind that God used that movie as an instrument to lead me to Salvation.
There have been many such movies produced over the years; one is coming out this week, "Noah" (you can see the trailer here in this link). I've also enclosed a link by the Gospel Coalition commenting on the movie; they take a balanced view on how Christians should approach it. Article.
People are welcome to boycott the movie but I would suggest a different approach. Take the movie for what it is: large parts are taken right out of the Bible, other parts are not. Please join me in praying that this movie might actually point people to the Scriptures, as it did for me many years ago, and that through general revelation people might come to know Jesus Christ.
They know the truth about God because he has made it obvious to them... Through everything God made, they can clearly see his invisible qualities-his eternal power and divine nature... Even Gentiles, who do not have God's written law, show that they know his law when they instinctively obey it, even without having heard it. They demonstrate that God's law is written in their hearts. (Excerpts from Romans 1 and 2)
Glorify God and enjoy Him forever!
