Can Christians write fantasy stories that involve magic?

There's nothing quite like making up a new world and allowing the characters to express every whim of your imagination and to have their abilities follow suit. Unfortunately, making people able to move the wind or practice "magic" has been a contentious issue among Christian circles. Some of you may recall some years ago when J.K. Rowling first started producing her famous Harry Potter books, many Christian groups were outraged at the plot being so centred around witchcraft-- a practice condemned in the Bible in several parts.

For example:

Deuteronomy 18:9-11

 When you enter the land the Lord your God is giving you, do not learn to imitate the detestable ways of the nations there. Let no one be found among you who sacrifices their son or daughter in the fire, who practices divination or sorcery,interprets omens, engages in witchcraft, or casts spells, or who is a medium or spiritist or who consults the dead.

2 Chronicles 33:6

He sacrificed his children in the fire in the Valley of Ben Hinnom, practiced divination and witchcraft, sought omens, and consulted mediums and spiritists. He did much evil in the eyes of the LORD, arousing his anger.

Micah 5:12
I will destroy your witchcraft and you will no longer cast spells.

Nahum 3:4
all because of the wanton lust of a prostitute, alluring, the mistress of sorceries, who enslaved nations by her prostitution and peoples by her witchcraft.

Galatians 5:19-21

¹⁹ The acts of the flesh are obvious: sexual immorality, impurity and debauchery; ²⁰ idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions²¹ and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.

Then the question comes out, is writing stories that contain magic a poor practice for Christians? What if those stories include Christian values and plot features geared towards pointing people to God? As a Christian writer, this is something I'm trying to figure out. After all, giving God my life in all that I do is very important to me, even if it means I have to change my stories.

Some famous writers that managed to blend the use of fantasy with Christian themes are J.R. Tolkien and C.S. Lewis. Tolkien even features a wizard as one of his key characters and yet many Christians use the imagery in The Lord of the Rings to express Christian themes such as fellowship and being willing to journey and face all odds for the call you receive. 

I've read these stories and I've enjoyed them. It has been a great mission of mine to use what I write to point to God, but at the same time I also just like making up stories that deal with people and how they interact. Magic just adds a bit of spice to it.

So, here are the cons so far that I've heard for including magic:

1) if you include magic in stories, you are promoting something that the Bible condemns. 

2) If you include magic, if you write anything expressly Christian afterwards, no one will respect you.

3) If you include magic, kids might read it and think that magic shown in this world is okay, such as the use of Ouija boards and the like. (Definitely do not want this!)

4) If you are spending your time writing fantasy, what are you really accomplishing for the kingdom of God? Even if you make it as though the magic is something that is given from a "God" figure, there is a lot of room for people to extract all sorts of principles that are not true in this world. For example, if I have a world where there is one God who gives people the ability to do things when they ask, this might rise the idea that God answers "yes" whenever people pray, which is not true all the time. 

On the other side, I've talked to people that think it's the messages that you send in a story that are more important. What values do you express? Won't there be undertones of what you believe in whatever you write? Also, the fact that it's meant to be in a different world all together is something I've heard as a pass for writers to be at liberty to make stories of this kind. Would being recognized as a writer open up doors in the secular world to share your faith? These are all things to be considered.

So reader, what do you think? Should including magic be avoided all together? Should it be used with care and the emphasis that there is bad magic out there? Comment below :)
