This is a loaded topic. My quest for truth has led me to various places. At one point I searched for truth in drugs and alcohol. The search really picked up when I put those things down. The high I felt was good but artificial. God filled me with his prescence and grace when I was totally broken and it was real and long lasting. I prayed to whatever would listen to me at the time and God answered. After that I was led to Christian circles on and off for over a decade. I found some answers in the church and others were not answered there.
Today I am not a practicing Christian but I do hold dear many things I learned and felt there, I haven't written them off either. I just felt that the teachings of God as a whole were not complete. I knew there was more and that some of the things I heard couldn't be true; such as everybody who doesn't believe in Jesus as God is going to hell. I walked away from that belief and am walking on virgin soil, looking for goodness in various faiths. As a note I found Bah'ai very interesting.
I am finding that as Jesus said,"the kingdom of God is within you", is very true. I'll tell you something, honestly seek God and you will be led in the right direction. Don't allow fear to creep into your mind, satan isn't causing you to ask questions, you are asking questions because something inside of you knows there is more. Don't give up.
