Every once in a while someone in my extended circle puts together the idea that I'm a Christian and a professional D&D writer and asks my advice on how I resolve conflict in those two things. The true, but uninformative answer is that there is no conflict, and now would you like some pie?
I don't usually give that answer, because it's not really the question being asked. The real question is, "I'm intellectually stuck between my religion and my joy. Can you get me unstuck?"
I usually can't, because that's between you and God, friend. But sometimes I can offer some helpful ideas the person hasn't come up with on his own. (It's always a dude.) Here are anonymized excerpts from what I wrote the other night to a friend who asked me that question:
Whenever I've talked with people about this kind of stuff, one of the primary things I try to get across is that God is the main thing. There's nothing particularly satanic about D&D/fantasy/speculative thinking, but if it's getting in the way of God, then God gets to win. I've talked to people who have a lot personally invested in D&D, and who, in conversations with family members, try to "win" their point. That's a tenuous place to even start, much less finish. God must be the main thing you're trying to get to, or else you're going to spin out on some useless tangent.
I find this to be true for me, and I suspect for you as well: There is something true and deep that fantasy sparks in you. Like pretty much everything in a world bent with original sin, it isn't inherently evil. Football, sailing, welding, D&D -- anything can be twisted toward evil if you go that way with it. It can also be straightened to bring out love and truth.
But since fantasy has particular meaning to you, it's more likely to do you good or ill than say, welding. Especially if it's affected you deeply enough that you've ever struggled with it.
Therefore, removing it from your life might protect you from harm. But it also walls off the potential good that could come. Which is more important to you? To God?
These are not rhetorical questions, and you might find they have different answers at different times. God might want you to back off from something at some point to protect you, but that doesn't mean God always wants that. That's why we have a new covenant. Jesus lets us replace law with relationship.
As a result, categorically eliminating things that have potential to be spiritually destructive becomes problematic. It creates a religion that forces you into a tiny, contorted shape.
Instead, look to a living, interactive God for answers, rather than a set of principles designed to protect you from evil. From this perspective, the way forward becomes: Spend as much time as you can going toward God, and as little time as you can trying to get away from evil.
The essential problem I have with the sorts of ideas concerned Christians typically espouse here is that they focus on the evil. That's not an inherently bad goal, but evil is a vanishingly small blot in the infinite light of God. If you're spending much energy on evil -- sensing it, fighting it, escaping it, protecting others from it -- you've started in the wrong place. You start from God. Then you depend on God to tell you if evil is going to be a problem. You don't need to suss it out yourself. God is the one in charge. Your job is to love on God.
God makes all things good. God will pull truth and love out of whatever you're in. There is nothing too "evil" for God to redeem; even genuinely evil things (without the irony quotes) can be redeemed.
If what you're doing wanders into sin territory, the Spirit will convict you about that. In the meantime, ferreting out sin is not your job.Your job is to love on God. Wherever you are, whatever you're into, count on God to make it good. Because He will. He does. All the time.
I'll end with scripture, since that's one of the means we're supposed to use to make sure we're not kidding ourselves with trumped up ideas. Philippians 4:8 says, "Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things."
If D&D points you toward true, noble, pure, lovely, admirable, excellent, and praiseworthy things, then think about D&D. If it does not, follow the thing that does point you toward those. Do not spend any more time on Satan than you must. God is sovereign, and knows what you need. Pay attention to God, and you will be steered well.
Interestingly, the real problem between Jesus and D&D -- which no one has ever asked me about -- is the idea that you solve problems and advance in the world by slaying your opposition. That methodology is wildly unChristlike. Killing your enemy is exactly the opposite of what Jesus said to do. It has no place in the Kingdom of Heaven. A major premise of the game is a lie.
But it's a fun lie, so I keep playing.
