I don't know if this is a recent development but it's always seemed to me there's a big divide between "CHRISTIAN" media and media that happens to have Christian themes.
In other words, The Chronicles of Narnia is a great story from a Christian's point of view. C.S. Lewis did not set out to nurture anyone's biases, make money off of religious people, or convert anyone. He just wanted to write a good story and who he was came through in the text.
Christian movies, music, and comics that get made these days are designed to push an agenda first and foremost, always at the expense of making the material actually good. Stuff like God's Not Dead or anything Kirk Cameron's made in the last twenty years has a built-in audience of people who will see it to have their biases confirmed. They also get tied up in gross political agendas that have more to do with specifically capitalist American Christian ideals, which are outright harmful to society and have little to nothing to do with actual Christianity.
I should probably come clean at this point and say I'm a non-believer who writes a satirical religious horror comedy called Andy Christ. I may not be the source you're looking for but my advice would be this: Don't start writing anything with the goal to "make people think." This is a mistake I've made a couple times myself and if you look at my comics, I think you can tell where I stopped making a conscious effort to do that and just be funny and let the story happen. People are insulted when they feel preached at. If you're a good writer, whatever you're trying to say will come through in smarter, more subtle ways, and it WILL make people think. But it's one of those things that if it's your goal, you shoot yourself in the foot.
Don't bill your comic as "Christian" because you don't know what kind of positive or negative assumptions people are going to project onto it. Like it or not, America has made "Christian" into a very politically charged word. An evangelical looking for a Christian comic and finding yours may be upset if you've got nothing to say about the evils of gay marriage and the war on Christmas. Others might see that your comic is "Christian" and skip it for the exact opposite reason; they may assume you'll be pushing that nonsense.
I also don't think you'd want to limit yourself to an audience of only Christians. The fact of the matter is if you strip Christianity of all its mythology and modern politics, you're left with a pretty decent set of philosophies for being a decent human being. Its values are largely universal, love thy neighbor, judge not, etc. You could write an entire story and never once use the words "Jesus" or "Christian" and still end up with a Christian story without alienating anybody or pushing an agenda.
