Well, for me personally, I would have to go by my testimony. To start off, I know that many people will only believe in God if they have hard-core evidence that they can see with their 5 senses, which is completely understandable because that interests me also. However, faith and miracles is what won me over for Christ. I grew up going to church my whole life, but I really never did accept Jesus as my Savior. I was abused at 4 years old and went through court cases for 8 years. I could go into detail, but I rather not. Many people told my mom and I that we would never win the court case because my old dad disposed of the evidence. I prayed and my mom prayed countless times a day. I know this may seem like a coincidence to some people because they don't want to believe in miracles, but for me and my family, we do. It wasn't a coincidence at all, believe it or not, God helped us to be strong in those times and he has blessed me with unbelievable talents. Anyways, like many of you though I like to know about the science of how Christianity can work. So far, I have seen nothing better proposed. I am still researching and learning though. I guess through this post, basically, personal experiences with God is what brought me to where I stand today.
