Need help devoting myself to god...i want to be an exorcist when i am older?

It's good that you want to get close to God, but by becoming an exorcist is not the way. If anything, by doing that, you'll be getting farther away from him and getting more closer to his greatest enemy -Satan. Some may say differently, but if you begin to study the Bible, you will see that this is true. Satan has deceived many people by means of the occult, and exorcism is included in there. Being an exorcist will endanger you in ways that you can't imagine. It will expose you to Satan's workers - the demons, and then gradually, they may become to take over your life. I'm not sounding dramatic, it's just that I want to warn you of what you can look forward to if you pursue this. You want to get close to God, start with prayer, studying the Bible, and searching for a religion that lives by what the Bible teaches. That way you will get close to him and find protection in this sick world and it's environment, and you'll start to have a real hope for the future, which is something that many people around the world have lost.
