When I was growing up, I did a lot of reading of fiction books.
I still read some fiction (though not nearly as much as I did when I was younger).
A lot of books purport to be "Christian" fare, but they either support false doctrine, a false gospel, use bad language, advocate women's lib., put men and women in compromising situations, appeal to lust, and have "Christians" who don't seem to care whether a potential spouse is a believer or not.
Also, there is very little fiction written by people who believe in the doctrines of grace and have solid Theological views.
What people write reflects their values and the teaching they have or have not received.
Sadly, much of the writing out there reveals the lack of solid Biblical knowledge and practical wisdom of many professing Christians.
Writers need to think about what they are writing and what its purpose is.
Will it lead people to sin?
Will it reflect godly truths and values or lead people to accept values that don't honor God?
Will it lead them to antinomianism (an abuse of grace) or legalism (works-based religion) or eisegetical false teaching?
Will your writing lead people to the Gospel and wise behavior, or will it lead them to sensuality, worldliness, and heresy?
Some would throw out fiction altogether, but even "entertainment" can be a subtle way to encourage each other to love and good deeds and obedience, present Biblical doctrine, and direct unbelievers to the Gospel.
It can be challenging, and yet, it can also be enjoyable.
It can reflect real struggles, but with a purpose.
There are some good books out there, but sadly they are few and far between.
I really believe that it would be a great idea for more book writers to run their writing by someone (or more than one person) who is doctrinally sound before having it printed or selling it in any format.
Even those of us who write blogs could use some feedback if we get way off track.
Whether it's for kids or teens or adults, I want to encourage those who do write to write for the glory of God, and as a result, what you write may influence people.
It may be more subtle, but it really can.
It's not a substitute for Bible study, but it can have benefits.
