I agree somewhat but I do think there needs to be some balance and diversity of strategies used to get the message across. Literature has always been a great way to transmit a message in a way that engages the imagination. Challenging messages doesn't necessarily need to be transmitted in challenging ways. Helping people understand why the message is important instead of a "take it or leave it" approach makes it easier to receive a message.
I like Christian romance fiction because it used romance to communicate the meaning of love and lived faith in the context of a relationship. It shows indirectly the effects of living through difficult circumstances or situations and learning how faith operates to encourage survival and personal feeling of empowerment and success.
I agree.
It's no longer just the message which needs to be considered but how to get it across. For example, those hell and damnation sermons may've been effective in getting people to convert but it also taught Christians in some ways to fear God in an unhealthy way, suggesting that God was only a God of judgment and punishment.
Don't get me wrong. When I'm talking about seriousness, I'm not talking about hell and damnation. (These are important topics that Jesus dealt with but he always provided the solution. In Christianity, good overcomes evil.) Instead, I'm talking about the very issues you mentioned that you wanted to be handled in the literature, the struggles that people today face. They are serious issues and require a proper understanding of the faith in order to tackle them in literature in a way that is both entertaining and instructive. The problem I see is that many Christians shy away from studying these issues and instead cling to "What would Jesus do?" while completely forgetting that he struggled with temptation as we did (though he did not succumb). This avoidance results in literature that creates caricatures instead of characters. We can't relate to them because their struggles lack depth. We are presented with characters who magically transform instead of characters whose virtues are forged.
On another note, I do feel that there are particular groups of Christians who are overly emphasized in the literature. For example, not all Christians believe in the rapture but thanks to Tim LaHaye's series one would think that every Christian agrees on how the book of Revelation should be interpreted. I completely avoid the Christian section of my bookstore because of the lack of representation of other opinions. It is funny how a group that makes up the minority of the world's Christians have so much influence.
I would also hope that books were written for audiences of varying levels of reading skill. Christianity has a long history associated with education. This is not the time to start dumbing things down. We should be raising standards.
