Is Christianity with reason wrong?

Is it wrong to try to reach God with reason instead of faith? I really believe that logical reasoning is the way to get closer to God but since I was a kid my parents and relatives keep telling me that I can only get closer to God and be saved by my faith and I'm not really a faith person, I'm more a logical person. I'm afraid I'm taking the wrong road, my mind keeps telling me I'm right thinking with reason but my parents and friends from church keep telling me I'm not going to be saved because of that. I've started studying Deism and I really like it, not everything, but it makes sense to me. Is there anyone that can make me understand more about Christianity and logical reasoning? PS: Am I going through a spiritual war or something like it? I'm really confused and a bit scared about my decisions and thoughts. Thanks in advance for any help.
