Religion is a tricky subject to try and rationalize since it's based entirely on the premise of faith. Frankly I've never been much a fan of practiced religion or the "institution" that it has become. It someone finds comfort in the belief if a higher power and treats that as their guiding star throughout their life to do right by others and themselves in order to sustain a sense of righteousness and worthiness, then I see no harm whatsoever in that way of thinking. You can look at one religion and cross-reference it with another, find similarities and products that are entirely different to one another. Each different interpretations of a power seemingly beyond comprehension, only capable of being referred to as "omnipotence."
There's a saying that suggests that the Bible is history's greatest best selling fictional novel. There's a part of me that wants to say "don't be silly, you don't know it's fiction, all about having faith." But that's not necessarily true if you really think about it. The Bible and similar texts all throughout the world have a similarity of being governed by the will and testament of a living "Prophet" whom claimed to know the will of "God." These Prophets were not God themselves, and no one ever saw or heard the same message they did supposedly. So who's to say it wasn't all made up, an episode of heat stroke, maybe they were just really good at pretending something was real that they fooled themselves into believe it too? Who really knows? It's all a matter of interpretation and whether or not you believe that to be actually possible.
So to really summarize the point, you can't "make" yourself believe in religion. You can follow it, pick and choose lessons of it to follow or even all together disregard it; maybe even make your life goal the achievement of debunking it like some people do. It all boils down to your own individual faith. You can entirely believe in God but not practice Christianity or any other religion, that's entirely possible and -contrary to popular belief- not something that would necessarily be wrong. I've heard a saying that each of us have our own relationship with God, so it'd be silly to suggest "if you don't live in the same house as him, then you can't be friends." You can ask the question and wonder to yourself about it without believing and still be able to go about living a life indifferent to the conclusion. Whatever makes you feel more comfortable and helps you view the world and the many intricacies it has.
