Are you sure your children think with a biblical world view rather than a humanistic world view? I notice that many children and young people of Christian and homeschooling parents watch a lot of movies. It would be best if they only rarely watched a good and wholesome movie. But if you allow them more, the challenge should be taken up to make sure they receive more time in God’s Word and prayer than they do of movies and the “spirit of the world.” Keep the right balance.
